Under the condition of meeting resolution, the SAR real-time imager can satisfy the demands of the processing band by pre-filter and down-sample.

综合孔径雷达(SAR)实时成像处理器，在满足分辨率的情况下，通过预滤波和降采样的方式降低数据率来满足系统处理带宽的要求。

Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.

然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。

其思路是将信号先通过单边带调制，将较低频率调制到需要的频率范围；然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。
