文中介绍采用集成化、模块化的设计思路和方法,研制了一种高度集成的L波段雷达超导接收机前端。以一体式超导开关滤波放大组件为核心部件,突破了超导-低温器件的小型化集成等关键技术,并实现超导接收前端12个信道的步进调谐选择功能,同时将整个前端的降温时间缩短至一小时内。样机与雷达系统进行联试及试用结果表明,该样机能够有效抑制雷达接收机带外干扰信号,提高了雷达目标探测能力。 In this paper, a highly integrated L-band radar superconducting receiver front end has been developed using integrated and modular design ideas and methods. The integrated superconducting filter switching amplifier components as the core components, breaking through the superconducting - the miniaturization of low temperature devices and other key technologies, and to achieve the front end of the superconducting receive 12 channel tuning function, while the entire front of the cooling Shorten the time to an hour. The prototype and the radar system were tested and compared. The results show that this prototype can effectively suppress the out-of-band interference of the radar receiver and improve the radar target detection capability.
