- Abstract:
- The clutter distribution of airborne bistatic radar varie with ranges due to the relative motion be-tween the transmiter and the receiver and the covariance matrix estimation is no longer accuate ,so that the sta-tistical STAP methods degrade. In this paper,a new clutter compensation algorithm for airborne bistatic radar is proposeu. This methou involves frist a pre-processing with Doppler warping methou to bring the clutter spectra together in the deriction of main beam and subquently Doppler compensation of different range gates in thedirection of multiple space angels.Simulation results show the proposed method can reduce the clutter nonho-mogeneity of bistatic radar effectively and is spuerior to the traditional compensation methods.
