Augmenting Synthetic Aperture Radar with Space Time Adaptive Processing
Wide-area persistent radar video o↵ers the ability to track moving targets. A shortcoming of the current technology is an inability to maintain track when Doppler shift places moving target returns co-located with strong clutter. Further, the high down-link data rate required for wide-area imaging presents a stringent system bottleneck. We present a multi-channel approach to augment the synthet...
متن کاملRadar Space-Time Adaptive Processing
Space-time adaptive processing (STAP) is a signal processing technique that was originally developed for detecting slow-moving targets using airborne radars. The general principle of STAP is as follows. The radar transmits a train of M coherent pulses. The echoes from potential targets (and clutter) are collected at each of the N elements of an antenna array. Separate receiver chains are attach...
متن کاملStatistical Signal Processing for Synthetic Aperture Radar
Synthetic Aperture Radar (SAR) currently has problems in the processing that lead to smearing of the image. We have developed a new method of processing the data using maximum likelihood theory that will remove the smearing leading to superior images. The goal of this project was to write a MATLAB program to simulate a SAR system to test the new processing method.
متن کاملBistatic Synthetic Aperture Radar Synchronization Processing
Bistatic synthetic aperture radar (BiSAR), operates with separate transmitter and receiver that are mounted on different platforms (Cherniakov & Nezlin, 2007), will play a great role in future radar applications (Krieger & Moreira, 2006). BiSAR configuration can bring many benefits in comparison with monostatic systems, such as the exploitation of additional information contained in the bistati...
متن کاملRobust adaptive signal processing methods for heterogeneous radar clutter scenarios
This paper addresses the problem of radar target detection in severely heterogeneous clutter environments. Speci0cally, we present the performance of the normalized matched 0lter test in a background of disturbance consisting of clutter having a covariance matrix with known structure and unknown scaling plus background white Gaussian noise. It is shown that when the clutter covariance matrix is...
