Attitude variations cause a Doppler shift and are corrected by limiting the processed azimuth bandwidth or by reversing the frequency shift with a range-dependent filter. Another important area considered is the effects of motion compensation on interferometry. When performing interferometry with YINSAR, motion compensating both channels to a single track has two effects. First, the applied MOCO phase corrections remove the "flat-earth" differential phase from the interferogram. Second, range resampling coregisters the two images. All of these changes have helped to improve YINSAR imagery.

Download Motion Compensation for Near-Range Synthetic Aperture Radar Applications Book in PDF, ePub and Kindle
The work focuses on the analysis of influences of motion errors on near-range SAR applications and design of specific motion measuring and compensation algorithms. First, a novel metric to determine the optimum antenna beamwidth is proposed. Then, a comprehensive investigation of influences of motion errors on the SAR image is provided. On this ground, new algorithms for motion measuring and compensation using low cost inertial measurement units (IMU) are developed and successfully demonstrated.

Download A Solution for Real Time Motion Compensation for SAR (Synthetic Aperture Radar) Without Using Inertial Navigation Systems Book in PDF, ePub and Kindle
This paper reports a new solution for real time motion compensation. The main idea is to extract all the necessary motions of the aircraft from the radar backscatter signal using a new radar configuration and new methods for evaluating the azimuth spectra of the radar signal. Hence an inertial navigation system becomes unnecessary for a lot of applications. The motion compensation parameters for real time motion error correction are the range delay, the range dependent phase shift and the pulse repetition frequency. The motions of the aircraft to be extracted are the displacement in line of sight (LOS) direction, the aircraft's yaw and drift angle and forward velocity. Results show that a three look image with an azimuth resolution of 3m in L-band using a small aircraft is achievable and the implementation of this method in real time using an array processor is feasible.
