线性调频无人靶机低空高度表设计

Design of Lower Space Altitude Meter for Pilotless Target Drone by Linear FM

针对无人靶机低高度表要求尺寸小、重量轻、功耗低、可维修性和可靠性高的特点 ,该文介绍了一种利用线性调频体制设计无人靶机低空高度表的方法 ,并对主要参数的选取和主要电路的设计原则进行了较详细的分析。经实验表明 ,只要解决好高效率低副瓣平板微波集成微带天线以及窄带跟踪滤波器等关键部件的设计 ,就能达到预定目的。

In view of small size,light weight,low power dissipation,maintainability and high reliability of the low space altitude meter for pilotless targetdrone ,a method of designing the meter by means of linear FM and analysed in detail in this article. Experiments show thatthe method isuseful forother designs,so long as the design of crux unit such as high efficient low side lobe plate microwave integrated microstrip antenna and narrow- band tracking filter are done well.
