Abstract

Bistatic synthetic aperture radar (BiSAR) is a space-variant system and the range resolution´s direction and the azimuth resolution´s direction are varying in space. Therefore the analytical calculation of the BiSAR resolution in arbitrary direction, especially in the coordinate axis direction, is needed. Several models related to range and Doppler are presented and analyzed along with the resolution cell. Fast approach to calculating the resolution in arbitrary direction for bistatic SAR with arbitrary geometry configuration is proposed. The simulation results are presented and the theoretical analyses are validated.
