一种雷达与电子侦察一体化多通道接收组件的设计

随着近年来现代电子技术的全面发展，针对射频前端单一器件模块级的小型化、高性能研究已初步凸显成效，但从系统层面出发统筹考虑设计低成本、高性能、小型化综合电子系统的研究报道还很少。从雷达和电子侦察基本工作原理出发，根据雷达和电子侦察各自的指标要求，对组件的链路和结构进行设计，提出了一种12通道的雷达与电子侦察一体化接收组件，给出了实物指标测试结果，所有通道噪声系数均小于3dB，雷达接收通道增益均在45±2dB，镜频抑制大于60dB；电子侦察接收通道增益大于20dB，相邻通道间的隔离度大于40dB。此次设计对未来实现更复杂的低成本、小型化高性能综合电子系统有重要意义。

Design of a multi-channel receiving module integrated radar and electronic reconnaissance

In recent years, the research on miniaturization and high performance of single device module level of RF front-end has initially achieved remarkable results with the full development of modern electronic technology. However, there are few research reports on the design of low-cost, high-performance and miniaturized comprehensive equipment from the system level. The link budget and structure of the module are designed firstly on the basis of working principles of radar and electronic reconnaissance. A 12-channel receiving module integrated radar and electronic reconnaissance is proposed according to the respective requirements of radar and electronic reconnaissance in this paper. The final measurement results of the proposed model are given. The noise coefficient of all channels is less than 3dB, the gain of radar receiving channel is 45±2dB, and the mirror frequency suppression is greater than 60dB; The gain of electronic reconnaissance receiving channel is greater than 20dB, and the isolation between adjacent channels is greater than 40dB. The work has great significance to realize a more complex low-cost, miniaturized and high-performance integrated electronic system in the future.
