本文叙述90GHz频段雷达/辐射计传感器用的微型抗大过载前端,论述了该毫米波硬件设计和工艺的技术现状。在同一传感器中采用有源无源复合工作,即使在复杂的杂波环境中,也具有识别有关目标的引人注目的特性。前端采用波导研磨块(milled block)工艺制作,其体积不到7cm~3,重量16g。其半个器件和整个分统系在过载高达16000g的条件下作了大范围的测试,试验结果表明,在结构和电气性能上均没有产生不允许的变化。 This article describes the 90GHz band radar / radiometer sensor with micro anti-overload front-end, discusses the millimeter wave hardware design and technology status quo. The use of active-passive compounding in the same sensor provides compelling features that recognize the target, even in complex clutter environments. Front end using waveguide milled block (milled block) process, the volume of less than 7cm ~ 3, weight 16g. A half-dozen devices and the entire subsystem were tested extensively under conditions of overload up to 16000g and the results showed that there was no unacceptable change in the structure and electrical properties.
