摘　　要：介绍了DBF体制雷达中多通道数字中频接收机的研制思路、方案 ,其基本思想是用中频直接采样和数字I/Q解调技术代替模拟I/Q解调 ;并应用LVDS技术解决DBF体制雷达系统中多信道、高速大容量数据的传输问题。详细分析了研制中的关键技术 ;给出了试验测试结果。The scheme for design a multi-channel IF digital receiver for DBF system radar is introduced in this paper. The analog I/Q demodulation is replaced by direct IF sampling and digital I/Q demodulation. The key technique of LVDS is used to solve the problem of high-speed multi-channel data transmission in the DBF system radar .The key design techniques of the receiver are analyzed in detail .The test results are also given in the paper.
