Analysis of AMTI performance for GEO-LEO system bistatic radar

The transmitter of GEO-LEO system spaceborne bistatic radar located in geosynchronous orbit, and the receiver located in low orbit, which has the advantages of large beam coverage, anti-stealth and anti-interference, and has great application potential. However, the feature of large beam coverage requires the detection efficiency. For improving the detection efficiency, the best beam coverage area should be designed. In this paper, the detection area is divided by transmitting beam and receiving beam for simulating the real beam irradiation condition and the clutter suppression ability is used as the evaluation index to find the change rule of detection performance and the best detection position of the detection region. The simulation results show that the detection effect is best when the azimuth angle of the receiving beam is 90°, and the regional detection performance gradually becomes better with the extension of the detection distance.
