Abstract

The precise point target reference spectrum of bistatic SAR has been a difficult problem for a long time. Many of the current available algorithms have approximation during deducing. This paper deduces the precise expression in Doppler- Frequency domain with the configuration of parallel flight paths and constant velocity of each platform. Then a new chirp scaling algorithm is put forward. At last, simulations are given to demonstrate the good focusing performance.
