引言在空-空和地-空导弹试验中,脱靶量测量仍然是最困难的问题之一。其所以困难是由于导弹的物理特性,导弹与目标的相对速度和测试人员不愿改变导弹特性(不用协同装置)等造成的。此外也由于在多数情况下靶机不能回收,机上不宜采用高级的测量设备。脱靶量测量中常用的两种方法是光学方法和雷达技术。摄影机、连续波调频雷达、连续波多普勒和极短脉冲非相干雷达都是目 Introduction Missing-target measurement remains one of the most difficult issues in air-to-air and surface-to-air missile tests. The difficulty is due to the physical characteristics of the missile, the relative speed of the missile and the target, and the unwillingness of testers to change the characteristics of the missile (without the cooperation of devices). In addition, because the target aircraft can not be recovered in most cases, advanced measurement equipment should not be used on the aircraft. Two methods commonly used in miss distance measurement are optical methods and radar techniques. Cameras, CW FM radars, CW Doppler and very short pulse non-coherent radars are all
