摘要
现代精密测量雷达多采用双通道接收机,文章从设计、使用的角度出发,对音频调制双通道接收机和0/π调制双通道接收机进行了讨论,并着重从测角体制上分析与比较这两种调制双通道接收机的性能及其特点。同时也指出了0/π调制双通道接收机应用中要注意的问题。文章最后还列出了双通道接收机角性能方面的实验数据。
Two-channels receiver is widely used in modern precision ins-trumentation radar.In the perspective of design and use,two-channels re-ceivers of both tone modulation and 0/π modulation are discussed in thispaper,and performances as well as features of two-channels receiver of thetwo modulations are analysed and compared with the emphasis on angle-measuring system.In the same time,the problems claiming attention in theapplication of two-channels receiver of 0/π modulation are shown.At last,the experimental data on angular performances of two-channels receiverare listed in this paper.
