Abstract

Bistatic configuration is an attractive concept for synthetic aperture radar (SAR) missions, which benefit from use of separated transmitter and receiver flying on different platforms. The processing of radar data stands out as a fundamental issue to facilitate bistatic SAR research and application in remote sensing. A bistatic processing algorithm based on Loffeld's bistatic formula (LBF) is proposed. The approach involved bistatic term compensation and quasi monostatic processing, and the latter part derived from a chirp z transform algorithm for monostatic case. As steps to a bistatic SAR processor for space configuration, this paper presents an approximation of transmitter/receiver slat range depending on individual incidence angle, and modifies range CZT parameter and azimuth compression operator. First results of this algorithm on simulated raw data are included.
