Air moving target indication (AMTI) using space based radar (SBR) is attractive. In order to detect airborne target in clutter and measure the target's range at the same time, SBR usually use medium PRF waveform. Theoretical analysis and experimental results show that range ambiguity cause target's range ambiguity and clutter's range foldover. Range ambiguity significantly degrades the clutter suppression...
In order to develop clutter mitigation techniques, clutter simulation and characteristics analysis is very important. By introducing the clutter model of space based radar (SBR) and discussing the earth's rotation effect to Doppler frequency, we get the space-time clutter spectrum of SBR. For illustration clutter characteristics, we plot clutter space-time spectrum and clutter angle-Doppler traces...
