提出了一种适用于合成孔径雷达的宽带数字接收机的实现方法。针对合成孔径雷达海量数据处理的特点，此宽带数字接收机采用了多相Hilbert数字变换的体系结构，通过此结构可以降低系统的吞吐量，满足系统实时性处理的要求。

In this propose, we provide a feasible implementation of broad-band SAR digital receiver. According to the large data processing volume of SAR, the receiver employs a framework based on muhiphase Hilbert Transform, which can reduce the system throughput and meet real-time processing requirement.
