摘要

针对接收机稀疏且配置不规则的寄生SAR系统无法直接利用空间信息进行抗干扰的问题，提出了一种利用空间信息进行抗干扰的新方法。该方法首先在每个小卫星上使用多通道SAR，然后利用非均匀数据重构成均匀序列，然后采用空时自适应处理而不是波束形成来消除干扰的影响。仿真结果表明了该方法的有效性。

Anti-jamming technique based on sampling reconstruction in parasitic spaceborne SAR system

For the problem of being unable to use spatial info directly to anti-jam in parasitic SAR system with sparse and irregular configured receivers, this paper proposes a new method to use spatial info. This method first uses multi-channel SAR on each small satellite, then uses the nonuniform data to reconstruct a uniform sequence, then uses space-time adaptive processing rather than beamforming to remove effect of jamming. Simulation result shows effectiveness of this method.
