Radar Parameter Design for Geosynchronous SAR in Squint Mode and Elliptical Orbit
TL;DR: Low-inclined elliptical orbits are recommended for geosynchronous synthetic aperture radar to map the regions of interest at middle latitudes, but the radius variation of such orbit results in a time-variant nadir interference and slant range of illuminated regions, which shorten the available imaging time for a specific pulse repetition interval (PRI).

A Modified Frequency Domain Algorithm Based on Optimal Azimuth Quadratic Factor Compensation for Geosynchronous SAR Imaging
TL;DR: A modified frequency domain algorithm based on optimal quadratic factor compensation, including phase and envelope compensation, is proposed in this paper to solve the problem of range cell migration in the range Doppler (RD) domain by traditional frequency domain algorithms.

A 2-D Nonlinear Chirp Scaling Algorithm for High Squint GEO SAR Imaging Based on Optimal Azimuth Polynomial Compensation
TL;DR: A 2-D nonlinear chirp scaling algorithm (2-D NCSA) based on optimal azimuth polynomial compensation is proposed to realize high squint GEO SAR imaging and computer simulations for different orbital positions validate the effectiveness of the proposed algorithm.

An Optimal Resolution Steering Method for Geosynchronous Orbit SAR
TL;DR: This study investigates an optimal resolution steering (ORS) method for GEO SAR, which differs from the total zero Doppler steering (TZDS) method, which attempts to minimize the Dopplers centroid.
