从理论上分析了Ａ／Ｄ直流偏移电平对双基地雷达检测的影响，并利用实际采集的双基地雷达数据验证理论分析的结果，给出了消除直流偏移后的检测结果。文末提出了一种改进双基地雷达接收系统的方案。

The influence of DC offset on bistatic radar detection will be discussed theoretically in this paper and the detection result will also be analyzed according to the real bistatic radar data. At the same time, the detection result will be given out with DC offset compensation. An improved receiving system scheme of bistatic radar will be shown in the end of this paper.
