LOW signal-TO-CLUTTER RATIO processing OF RADAR signalS

LOW SIGNAL-TO-CLUTTER RATIO PROCESSING OF RADAR SIGNALS

In radar problems involving weak signal detection conventional space-time processing cannot be used to separate the target from the clutter when the spatial and Doppler spectra of the target and clutter overlap. In such problems the concept of the locally optimum detector (LOD) is useful in coming up with a decision rule to discriminate between the two hypotheses of signal present or signal absent. The clutter, which may be correlated, can arise from either a non-Gaussian or Gaussian random process. For correlated multivariate K-distributed clutter it is shown in this paper that performance improvements can be obtained with an LOD receiver compared to the conventional Gaussian linear receiver.

A new exact recursive filter is derived for nonlinear estimation problems. The new nonlinear theory includes the Kalman filter as a special case. This filter is practical to implement in real- time applications, and it has a computational complexity that is comparable to the Kalman filter. The measurements are made in discrete time, but the random process to be estimated evolves in continuous time.

An algorithm for the automatic formation of tracks is developed for maneuvering targets in cluttered environments. This track formation algorithm consists of Integrated Probabilistic data Association Filters (IPDAFs) in an Interacting Multiple Model (IMM) configuration, and it is referred to as the IMM-IPDAF algorithm. The IMM portion of the IMM-IPDAF will consist of several filters based on different dynamical models to handle target maneuvers. Each of the filters will be an IPDAF to deal with the problem of track existence in the presence of clutter. Although the primary purpose of this paper is to deal with the track formation problem, the IMM-IPDAF can also be used for the maintenence of existing tracks and the termination of tracks for targets when they disappear. For illustrative purposes, simulations will be used to compare the performance of the IMM- IPDAF algorithm to other track formation algorithms. © 1994 SPIE. All rights reserved.

This paper derives a likelihood-ratio detector for bivariate time-series data having target- and correlated non-target-bearing components with randomly distributed, single-cell spike noise in one or both channels. After defining the detection problem explicitly, the detector is constructed as an analytic expression. A specific implementation of the approach is presented using a bivariate first-order autoregressive model for the correlation structure of the data. A computer model for the detector is constructed, and results using simulated data verify the usefulness of the approach in removing strong pike noise without damage to the target signal.

Within an Air Traffic Control (ATC) context many applications exist for off-line trajectory reconstruction such as evaluation of tracking or navigation systems and accident/incident investigations. Since the introduction of Jump-Linear models and associated filtering techniques enabled significant improvements in tracking small targets with useful applications to ATC one may expect that parallel developments in smoothing for Jump Linear systems enable similarly useful applications to aircraft trajectory reconstruction. The aim of this paper is to evaluate the validity of this expectation.

SPATIAL signal-processing FOR INFRARED DETECTION

SPATIAL SIGNAL-PROCESSING FOR INFRARED DETECTION

We conduct a comparative study of the performance of a variety of spatial filtering techniques for detecting small targets against infrared terrain backgrounds. We consider parametric and nonparametric filters as well as an example of a robust estimation technique as applied to a parametric filter. In addition, we consider the effects of a clustering algorithm on filtering performance. Some of the filtering algorithms that we consider are matched filters, Laplacian filters, quadratic filters and the Robinson filter. Several filter dimensions are considered as well as the effects of a guard band. These algorithms are tested against the Lincoln Laboratory Infrared Measurement Sensor database which is comprised of high resolution dual band (3.5 to 5.2 (mu) , and 8 to 12 (mu) ) data taken at a variety of sites under a broad spectrum of atmospheric conditions and times of day. Target insertion effects are modeled carefully, incorporating the straddling of targets across adjacent pixels as well as the effects of diffractive blurring. We find that many of the filters that we have tested show similar performance and all are clutter limited.

GATE SIZE FOR SEQUENTIAL MOST PROBABLE HYPOTHESIS TRACKING

GATE SIZE FOR SEQUENTIAL MOST PROBABLE HYPOTHESIS TRACKING

ISBN: (纸本)0819415391

The choice of gate size depends on the type of data association algorithm used and the optimization criteria. A prior well known analysis has presented a practical gate size for tracking approaches that sequentially select the most probable hypothesis. This paper revisits that analysis and presents an alternate approach. The intent of the gate sizing in this paper is to design the largest gate that eliminates any observation from the gate whose hypothesis probability is less than the null hypothesis probability. A study of the two approaches to sizing a gate reveals a dilemma and inconsistencies that under further scrutiny are resolved for reasonable conditions by decomposing the null hypothesis into two hypotheses.

In this paper, an approach to the automatic detection of vehicles at long range using sequences of thermal infrared images is presented. The vehicles in the sequences can be either moving or stationary. The sensor can also be mounted on a moving platform. The target area in the images is very small, typically less than 10 pixels on target. The proposed method consists of two independent parts. The first part seeks for possible targets in individual images and then merges the results for a subsequence of images. The second part of the algorithm specifically focuses on finding moving objects in the scene.

The Litton data Systems Vector Neural Network (VNN) is a unique multi-scan integration algorithm currently in development. The target of interest is a low-flying cruise missile. Current tactical radar cannot detect and track the missile in ground clutter at tactically useful ranges. The VNN solves this problem by integrating the energy from multiple frames to effectively increase the target's signal-to-noise ratio. The implementation plan is addressing the APG-63 radar. Real-time results will be available by March 1994.

Fourier synthesis method of waveform generation for ultra wideband (UWB) radar overcomes several disadvantages of traditional impulse generation. In this method a signal is generated in frequency domain by summing the relatively low power harmonics of the desired signal instead of generating it by a single high power source in time domain. In this paper waveform generation is extended beyond simple baseband periodic pulses. Method for generation of complex amplitude coded baseband waveforms with accurate control of pulse shape and pulse repetition interval is described. This waveform allows pulse compression and coherent integration of UWB signals and thus further reducing the need for very large power sources which may be required for conventional impulse radar implementation. The paper also presents a UWB radar concept which incorporates frequency domain waveform generation. signal processing issues for target detection are also addressed.
