Beam Motion Induced Doppler Shift of an Extended Object.
Abstract
A technique to synthesize radar echo on a pulse to pulse basis is introduced. It is applied to the analysis of ground reflections where an extended object is present. Since the extended object reflects the radar illumination in a regular manner from pulse to pulse, it introduces phase shifts into the echoes and makes the echoes appear to come from high speed target. The impacts of this phenomenon on the performance of systems which rely on Doppler filtering should be assessed in the future. Furthermore, since this phenomenon is expected to occur when slow moving extended objects such as sea swells are present in short ranges, it is important to take this phenomenon into consideration when weapon systems for ship self defense are deployed.
