Abstract EN
The bistatic configuration with a geosynchronous orbital SAR (GEOSAR) transmitter and unmanned aerial vehicle SAR (UAVSAR) receiver can continuously image in any dangerous and interesting district.
In this paper, the new imaging method in the case with the smaller orbital inclination of geosynchronous earth orbit and the steering beam working mode of UAVSAR was mainly studied and analyzed.
GEOSAR can be approximately expressed as a static state, and only the receiver provides all the Doppler information.
UAVSAR works in the steering beam modes, such as spotlight, sliding spotlight, and TOPS (Terrain Observation by Progressive Scan) mode.
The azimuth bandwidth increased by the steering beam causes an aliasing situation in the azimuth frequency domain.
To solve this problem, the proposed imaging method corrects the azimuth frequency aliasing using the scaling transform and the bulk azimuth compression.
Compared with the traditional imaging method, the simulation validates perfectly the effectiveness of the bistatic imaging algorithm.
