现代雷达系统对接收机提出了更高的要求,数字化接收机能满足这些要求并已经成为现代雷达、通信等接收系统的一种主流实现方式。文中研究了数字接收机,重点讨论了模拟接收机与数字模块的匹配、增益的计算和分配。根据设计要求,给出了一种模拟接收机详细设计方案,进行了各部分分析计算和详细设计,按照设计方案进行了工程样机研制,调试完成后给出了测试结果。测试结果表明:模拟接收机指标完全满足设计要求,并应用到了样机系统中,且工作稳定可靠。

Higher performance is required in a modern radar receiver. Digital receiver can meet the needs and it has been an effective implementation method for radar and communication systems. The digital receiver is discussed in this paper, the match of analog receiver and digital module, the calculation and allocation of gain are focused on. A detailed design of analog receiver is presented according to special requirements. The analysis, calculation and detailed design of all units are made, an analog receiver example is developed and the test results are given after debugging. The test results show that the performance of the analog receiver example meet the needs of the design. It has been used in an example system and works stably and well.
