In this paper, an algorithm using keystone transform and subaperture processing is proposed for focusing synthetic aperture radar data in highly squint angle and high resolution. The whole processing of the proposed algorithm consists of two main steps. Firstly, the keystone transform is used to remove the linear range walk to reduce the range-azimuth coupling of the echo signal. Afterwards, the space variant residual range cell migration (RCM) and azimuth modulation are compensated through a subaperture DFT processing, where the corresponding relationship of the Doppler frequency and azimuth angle is utilized. The proposed algorithm can process SAR data under a squint angle 80° and the resolution 0.5m, demonstrated by the experimental results of the simulated data. © 2019 IEEE.

Bidimensional empirical mode decomposition (BEMD) method is considered advantageous for analyzing non-stationary and non-linear signals. Recently, it has been introduced in non-stationary high resolution Synthetic aperture Radar (SAR) image processing. This letter proposes a new method for fusing high resolution Synthetic aperture Radar (SAR) and Panchromatic images, based on BEMD method. Under this method, first, multi-resolution decomposition images are obtained, from the original images based on BEMD algorithm, the features of the original images are separated into multiple scales of spatial frequencies, called intrinsic mode functions (IMF), and then an area-based image fusion scheme is applied to fuse the images at each decomposition level. Experimental results from GaoFen-1 (GF-1) Panchromatic and COSMO-SkyMed SAR images show that the proposed method not only preserves the high spatial resolution of Panchromatic image, but also combines the target and surface information in SAR image, which are difficult to identify in the Panchromatic image. The new algorithm outperforms the wavelet transform and non-subsampled contourlet transform (NSCT), in terms of both visual effect and quantitative analysis. © 2019 IEEE.

The three-dimensional (3D) radar can detect 3D information of air targets, including range, azimuth and height. It is considered as an important equipment of the air defense detection system in various countries. The precision of target height measurement is the key challenge in radar detection due to the influences of the complex background environment of air targets. This paper considers the background knowledge during target detection. By using the background knowledge of radar position meteorological parameters and multi-dimensional radar position RAG maps etc., this paper proposes an integrated software processing method to improve the precision of target height measurement for 3D radar and designs a height confidence evaluation model to improve the fusion precision of height information in the superior command unit of the radar. © The Authors, published by EDP Sciences 2018.

This paper presents a 3mm frequency band power amplifier based on the technology of SiGe BiCMOS. A fully differential structure consisting of cascode was adopted, and transformer match was used to achieve good performance and save areas. Measured peak gain is 4.7 dB at 101 GHz, with a 3 dB bandwidth of 23 GHz from 87 GHz to 110 GHz. The input and output return losses are less than-7.4 dB and-7.6 dB, respectively. The isolation is less than-27.4 dB in the 3 dB bandwidth range. The simulated result of output 1dB compression point power is 5.1 dBm at 94 GHz. The chip size is 1.15 mm×0.7 mm (including input and output test baluns and pads), which can be applied to radar, communication, imaging and other fields. © 2022 IEEE.

The Fast Fourier Transform (FFT) plays an important role in Digital Signal Processing (DSP). Compared with out-of-place FFT, in-place FFT has more advantages in solving conflict between the memory requirement of ultra-long FFT and the memory size of DSP. In this paper, a method of fast implementation of ultra-long in-place FFT is proposed. Bit-Reverse Loop technology is used in in-place 1-D FFT while improved matrix transpose technology is used in 2-D FFT. The experiment result on TMS320C6678 shows that the proposed method is effective. © 2019 IEEE.

Fast factorized back projection (FFBP) is capable to be applied almost in all kinds of SAR imaging. However, due to the residual motion errors (RME) preserved in the SAR images, autofocusing must be carried out under the framework of FFBP to achieve high-quality SAR images. In this paper, a new autofocus method is proposed based on FFBP algorithm. It explores the point-like targets distributed in the defocused images to get the first derivative of the RME, and then by an integration operation, the RME is obtained. Simulated and real SAR data are used to demonstrate its feasibility and effectiveness. © 2019 IEEE.

Sea Radar is an important technical measure for protecting national maritime resources and island sovereignty. The calculation of sea target velocity and course is important to monitor and track sea targets for sea radar, for calculation precision is directly related to the tracking effect of sea target. This paper systematically studies the problem on calculation of sea target velocity and course for sea radar, explicates the relevant technical principles, proposes effective algorithms for calculating sea target velocity and course based on multi-frame accumulative information, and gives a corresponding solution suitable for the scenario of sea target maneuvering. Finally, based on comparison analysis of real radar data and Automatic Identification System (AIS) data, we verify the precision of our algorithms. © The Authors, published by EDP Sciences 2018.

An ultra wideband wide-angle scanning phased array antenna is designed. It is a banyan tree antenna, of which the radiation curved arm is obtained by stretching a closed envelope which is compose of three exponential curves and a straight *** gradually changing exponential curve envelope of the radiating curved arm greatly expands the impedance bandwidth. Simulated results show that in the frequency band of 30 MHz ∼ 100 MHz, the active voltage standing wave ratio (AVSWR) scanned from 0° to 60° in azimuth plane and from 0° to 30° in elevation plane are all less than 2.5. The simulated 10 × 6 array antennas have excellent ultra wideband wide-angle scanning characteristics. © 2024 IEEE.

The altitude of the missile-borne radar seeker relative to the illuminated region is a significant parameter for the geometric correction in synthetic aperture radar (SAR) imaging. Error in altitude causes geometric distortion, which affects the performances of the subsequent scene matching and the target identification in SAR. Conventional radar altimeter with the down-looking antenna is not appropriate for missile-borne radar seeker with the forward antenna. To circumvent this problem, a Range-Doppler based Altitude Estimation algorithm (RDAE) appropriate for front-downward illumination is proposed based on the geometrical relationship between the relative altitude and the Range/Doppler between the platform and the illuminated region. The performance of the RDAE is investigated through simulation, and the results show that the RDAE has high estimation accuracy. © 2019 IEEE.

Mapping, monitoring and parameter inversion in the mountain areas covered with dense vegetation as well as cloud and mist is always a complicated subject. Synthetic aperture radar (SAR) is an effective sensor of great potential to solve this problem. In this paper, a high resolution P-band airborne SAR system is developed, which is the first quantitative airborne P-band SAR system for business operation in China. The inherent signal ambiguity phenomenon for wide beam radar system is discussed, and the solution is suggested and validated with this radar system. Then a flight campaign is launched with this P-band SAR system in the Southwest China. The defocusing introduced by the dramatic terrain undulations is analysed detailedly. By co-registering the external digital elevation model (DEM) to the SAR image and motion compensation, the refocused quality of the polarimetric SAR images satisfies the user's requirement. After polarimetric and radiometric calibration, the polarized composite and geocoded image products are obtained for further studies. With this P-band airborne SAR system, the repeat-pass interferometric data are expected to be collected in the future for the vegetated mountainous area, and it will play more important role in the fields of topographic mapping and deformation monitoring. © 2024 COPYRIGHT SPIE.
