针对反辐射激光近炸导弹,设计了一套简单低成本的脱靶量测量方法,从硬件总体设计到计算过程进行了较为详细的分析。根据激光引信触发信号通过遥测数据下传这一特点,利用触发信号时间作为关键点,将统一测控系统装备测量到的弹、靶GPS数据经与地面GPS基准站的数据进行差分处理后,实现对弹、靶遭遇轨迹的精确测量,通过计算得到脱靶量测量结果。试验证明利用GPS测定脱靶量,测量精度高,可以在靶场逐步试验推广。

A set of simple and low-cost miss distance measuring system is designed for anti-radiation laser proximity missile.The general hardware design and the computing process are described in detail.Based on the characteristic that the laser fuse trigger signal is transmitted by telemetry data,and using the time of trigger signal as the key point,the meeting-track between the missile and the target is accurately measured through the differential processing of the missile and target GPS data measured by the universal telemetry and control system and the data of ground GPS station,and then the miss distance measurement result is calculated.The test results prove that the GPS measurement method achieves high miss distance measurement precision and its application can be expanded gradually to ranges.
