Abstract:

Space-air based bistatic radar (SABBR), as one kind of new early warning radar, has many virtues such as big detecting area and strong anti-jamming ability. Firstly, the geometric model of SABBR is built. Then the models of target echo, clutter and through wave are built, their range and Doppler properties are analyzed respectively. Finally the relation between Doppler frequency and angle of target flying velocity, space-time clutter spectrum, space-time spectrum of target echo and through wave are simulated. The theory and simulation results show that the built models are reasonable and can provide reference for the study of SABBR key techniques.
