Abstract

Abstract:

In actual environments, the vertical height between airborne transmitter and airborne receiver is always different, and as a result, a vertical baseline appears between the two airplanes. This paper first analyses the common frame of bistatic airborne radar, and then takes bistatic airborne radar as a special example, which shows the influence of the clutter Doppler frequency from the different height between the two airplanes. The paper carries out computer simulation on four key models of bistatic airborne radar, and then explains the influence of the vertical baseline based on the clutter spectrum analysis. It is discovered that bistatic airborne radar with a proper vertical baseline will decrease the dependence of the clutter spectrum on range and improve the ground moving target indication performance.

Key words: bistatic airborne radar, vertical baseline, Doppler frequency, range dependence
