In this paper, we introduce the 2-D continuous wavelet transform (CWT) as a tool for the detection stages of an SAR ATR system. We demonstrate that the 2-D CWT tuned to reasonable target sixes can enhance the signal to clutter ratio (SCR) and improve detection performance in a focus of attention (FOA) algorithm as compared to the traditional CFAR algorithm. We also show that the 2-D CWT can be used to estimate the sire and pose of a target, which can provide important features for second level detection. The detection and feature extraction algorithms were tested on measured one foot resolution SAR data.

conference on radar sensor technology II

ISBN: (纸本)0819424811

Ground penetrating radar (GPR) is becoming an increasingly useful tool for road subsurface characterization. The Florida Department of Transportation (FDOT) has recently obtained a new 1 GHz ground penetrating radar with the ability to make high resolution measurements. Depth profile scan rates of the new radar are about 50 scan/sec and the radar operates on a test van travelling at speeds up to 50-55 MPH. The time domain data collected by the GPR allow the determination of thickness of the road surface and subsurface layers and, with appropriate signal processing, the data can provide information about voids and other anomalies within road layer interfaces. This paper will describe the salient features of the Florida DOT ground penetrating radar, recent measurement results, and applications of GPR for road assessments. It will also describe preliminary results of a University of Florida project which is employing advanced signal processing techniques to detect and classify subsurface anomalies in road layers. As a precursor to anomaly detection we are developing improved techniques for Finding road layer thicknesses and dielectric constants, The processing techniques being developed include matched filter and slope detection algorithms. A goal of the current work is to develop signal processing techniques that will allow FDOT to evaluate subsurface conditions for large sections of roads throughout Florida in a more accurate and rapid manner. It is expected that the GPR and the results of current research will assist the FDOT in more accurately determining road layer thickness profiles, in assessing road subsurface conditions with less coring, and aid in rehabilitating roads with less manpower than is now required, Such capabilities will allow potentially serious problems to be corrected before they become costly and will also provide a useful tool for future road design and improvement.

conference on Signal and data Processing of Small Targets 1997

Small targets defined in the paper are low-RCS targets or weak infrared emitting targets which are very difficult to track by a single sensor (a radar or an IRST) because the measurements gained by the sensor are usually unsuccessive. Although a single sensor can only observe the target in unsuccessive way, the sensor mt may sometimes track the target continuously by data fusion of the fractional trajectories or hits of the target from all sensors of the netted system. Typically, data fusion method of a distributed sensor net is track-to-track fusion that requires continuous track-level data(space vector estimates and their covariance matrices) from sensors in the net. For the case of small targets this condition can not be satisfied. In the paper, we derive a method to fuse the data of the small target from the system. The method includes data association and tracking. Special attention is pay to track initiation with Hough Transform for the association algorithm. Test and results are also given in the paper.

4th conference on Cockpit Displays - Flat Panel Displays for Defense Applications

作者： Adam, EC McDonnell Douglas Aerospace (United States)

ISBN: (纸本)0819424722

A cockpit revolution is in the making. Many of the much ballyhooed, much promised, but little delivered technologies of the 70's and 80's will finally come of age in the 90's just in time to complement the data explosion coming from sensor and processor advances. Technologies such as helmet systems, large flat panel displays, speech recognition, color graphics, decision aiding and stereopsis, are simultaneously reaching technology maturities that promise big payoffs for the third generation cockpit and beyond. The first generation cockpit used round dials to help the pilot keep the airplane flying right side up. The second generation cockpits used Multifunction Displays and the HUD to interface the pilot with sensors and weapons. What might the third generation cockpit look like? How might it integrate many of these technologies to simplify the pilots life and most of all: what is the payoff! This paper will examine tactical cockpit problems, the technologies needed to solve them and recommend three generations of solutions.

For the survey and inspection of environmental objects, a non-tactile, robust and precise imaging of height and depth is tie basis sensor technology. For visual inspection, surface classification, and documentation purposes, however, additional information concerning reflectance of measured objects is necessary. High-speed acquisition of both geometric and visual information is achieved by means of an active laser radar, supporting consistent 3D height-(i.e. range) and 2D reflectance images. The laser radar is an optical-wavelength system, and is comparable to devices built by Erim, Odetics, and Perceptron, measuring the range between sensor and target surface as well as the reflectance of the target surface, which corresponds to the magnitude of the back scattered laser energy. In contrast to these range sensing devices, the laser radar under consideration is designed for high speed and precise operation in both indoor and outdoor environments, emitting a minimum of near-infrared laser energy. It integrates a laser range measurement system and a mechanical deflection system for 3D environmental measurements, This payer reports on design details of the laser radar for surface inspection tasks. It outlines the performance requirements and introduces the measurement principle. The hardware design, including the main modules, such as he laser head, tile high frequency unit, the laser beam deflection system, and the digital signal processing unit are discussed. The signal processing unit consists of dedicated signal processors for real-time sensor data preprocessing as well as st sensor computer for high-level image analysis and feature extraction. The paper focuses on performance data of the system, including noise, drift over time, precision, and accuracy with measurements. It discusses the influences of ambient light, surface material of the target, and ambient temperature for range accuracy and range precision. Furthermore, experimental results from inspection of bu

Motion estimation in ISAR focusing

Motion estimation in ISAR focusing

conference on radar Processing, technology, and Applications II

ISBN: (纸本)0819425834

Inverse-Synthetic Aperture radar (ISAR) processing algorithms require an explicit or implicit model of the motion of the target, since this information is not measurable at the sensor. A major unsolved problem is whether it is better to develop a deterministic model of the motion or to fit the observations to a mathematical model which may be ambiguous with a wide range of physical target motions. This question is particularly important for the imaging of small targets in ground clutter since the available information on the target motion may be very limited. By contrast, the imaging of large ships in sea clutter yields a wealth of information of the motion of the body. This paper explores the effectiveness of models of the second kind by testing a set of motion estimation algorithms against motor vehicle targets imaged by a high-frequency SAR at long range and low grazing angle. The algorithms attempt to estimate the bulk motion of the vehicle and its rotation about its mean position by fitting many small pieces of information gathered from low quality or short duration scatterers detected in either the raw range-compressed signal history or in the complex image. In forming the motion model, the algorithm avoids undue reliance on particular bright or narrow-Doppler targets in favor of a global fit to many partially resolved or glinting features. The algorithm is demonstrated for 0.3 meter resolution SAR data of a Winnebago van from a Ku-band radar.

Integrated maritime surveillance (IMS) for the Grand Banks

Integrated maritime surveillance (IMS) for the Grand Banks

Oceans 97 MTS/IEEE conference

作者： Moutray, RE Ponsford, AM Raytheon Canada Ltd Waterloo Canada

ISBN: (纸本)0780341082

June 1997 will see the launch of a new approach to surveillance of the 200 nautical mile Exclusive Economic Zone (EEZ). Work on a demonstration system off Canada's east coast began in March 1996. This collaborative project is the result of more than a decade of research and development. The demonstration system will provide continuous, all-weather surveillance of aircraft, surface vessels, icebergs and environmental conditions in the Grand Banks region to beyond the 200 mile limit. Shore based HF surface wave radar is the key sensor in the new system. This is the only technology that can provide continuous, cost effective, over-the-horizon surveillance at such long ranges, Re-using existing systems is a key element in the development strategy. These potentially include reports from Coast Guard and Fisheries patrol vessels, patrol aircraft, Automatic Dependent Surveillance (ADS) reports from Coast Guard and fishing vessels and imaging satellite data. Surface wave radar provides the backbone picture by detecting and tracking all targets in the region but inputs from the other systems are essential in classifying and identifying the targets. Evaluation of the east coast system will include operation under extreme weather and sea state conditions, surveillance and management support to the east coast fisheries, enhanced visibility of tanker and support traffic to and from the Hibernia and Terra Nova oilfields, detection and tracking of icebergs and enhanced support for search and rescue and drug interdiction operations.

High speed 3D profiling is a key issue for many quality control systems in the manufacturing industry. 3D profiling in speeds that match the production demands of today's industries is very hard to achieve using conventional sensor technology. The solution presented in the paper is a sheet-of-light range imager based on a smart vision system. The 3D profiling system is based on a programmable smart vision sensor. The sensor consists of an image sensor, AD-converter, and RISC-processor integrated on the same silicon chip. The processor, being a line parallel bit-serial SIMD machine, handles both binary and grey scale information efficiently and has proven to be very suitable for sheet-of-light range imaging.

Proceedings of the 1997 IEEE National Aerospace and Electronics conference, NAECON. Part 1 (of 2)

作者： Cheng, Hongwei Mo, Longbin Sun, Zhongkang Natl Univ of Defense Technology Hunan China

Conventional target association and tracking techniques such as PDA and JPDA have very fine performance when the measurement acquired from sensors are perfect. However, when jamming and stealth techniques are widely used, it is very difficult for sensors to gain perfect measurements. Though a single sensor in a distributed sensors system might fail to acquire continually perfect measurements of low-RCS (stealth) targets under jamming environment, the distributed sensors system might gain relatively perfect measurements by integrating measurement hits or fractional trajectories of targets from every sensor in the system. The paper discusses association and tracking techniques under the circumstances mentioned above. Special attention is paid to track initiation and data association. Monte Carlo simulation test results are also presented in the paper.
