Effect of Range Ambiguity on Space BasedAMTI Clutter Suppression and Mitigation Method

摘要：

Air moving target indication (AMTI) using Space Based Radar (SBR) is attractive. In order to detect airborne target in clutter and measure the targetˇs range at the same time, SBR usually use medium PRF waveform. Theoretical analysis and experimental results show that range ambiguity cause targetˇs range ambiguity and clutterˇs range foldover. Range ambiguity significantly degrades the clutter suppression performance. A method based on orthogonal waveform for mitigating the range ambiguity effects is presented in this paper. The orthogonal waveform is launched in sequence. Then multi-channels matched filter is used to receive the replay pulse. Experimental results illustrate that the method is effective.
