一种靶弹装配检测雷达系统

A Radar System for Detection of Target Missile Assembly

位于靶弹弹体内的龙伯球装配正确性与否将直接影响靶弹的使用性能,本文设计一种用于靶弹装配生产线使用的检测雷达系统,该系统采用2.1GHz频率的连续波体制,结合小型微波暗室的使用,实现靶弹内龙伯球正、反向装配时雷达输出信号电平大小差别10倍以上,可以有效检测龙伯球装配的正确性,并具有操作简便、体积小、可靠性高、成本低的特点。

The correctness of the assembly position of spherical Luneberg-lens inside target missile is of paramount importance for the service performances of the target missile.A radar system for detection of target missile assembly in production line was designed to determin the correctness.The system is a continuous wave radar with 2.1GHz operating frequency,the combined use of this system with small anechoic chamber could achieve ten-fold difference or above of the output signal levels of radar system when spherical Luneberg-lens assembled forward and reverse inside target missle,thus the correctness or inaccuracy of assembly position could be detected.The system is characterized with easy operation,small volumn,high stability and low cost.
