摘　　要：本文给出了一种接收系统设计。该接收系统采用4通道干涉仪获取目标方位信息。通过优化接收系统的设计方案,对接收系统动态、增益、噪声系数等指标进行了分析。接收机实测指标说明该接收机具有灵敏度高、测向精度高、截获概率大等优点。Design of a receiving system is presented. This receiving system employs 4-channel interferometer to obtain target’s azimuth information. The index including dynamic range, gain, noise figure of receiving system are analyzed by optimizing design scheme of receiver system. The real measured receiver index shows that the receiver has advantageous like high sensitivity, high accuracy of direction finding and high interception probability.
