一概述在导弹靶试中,脱靶量是一个很重要的参数。用光学法测量虽然是一种好的方法,但是处理的时间太长,在距离较远时,精度也较差。脱靶量指示器,国内目前尚未研制成功。本文介绍的用多普勒信号计算脱靶量的方法,只要试验产品能通过遥测系统,向地面设备提供多普勒信号,就可以利用地面计算机,很快计算出脱靶量。因此,这一方法不仅可以直接用于某些试验(包括不宜安装脱靶量指示器的伞靶试验),而且也是脱靶量指示器的一种较好的设计方法。在弹上设备中,这一方法也可以用作获取脱靶量信息,以提高引战配合效率。文中对实际试验进行的一些计算表明,这种方法的误差有可能达到1～2米。
Overview In missiles, miss distance is a very important parameter. Although optical measurement is a good method, but the processing time is too long, the distance is far, the accuracy is poor. Off-target indicator, the domestic has not yet been successfully developed. This article describes the method of calculating the amount of miss distance using Doppler signals. As long as the test product can provide Doppler signals to the ground equipment through the telemetry system, the ground computer can be used to quickly calculate the amount of miss distance. Therefore, this method can not only be directly used in some experiments (including the umbrella target test should not be installed miss distance indicator), but also a miss distance indicator a better design method. In the device on the bomb, this method can also be used to obtain miss distance information to improve the efficiency of the lead war with. Some calculations made in this paper show that the error of this method is likely to reach 1 ~ 2 meters.
