靶场高精度脱靶量测量方案与仿真实现

针对靶场目前飞行器系统脱靶量测量存在使用条件的限制、不能满足试验要求的问题,提出一种将双天线分集接受、伪距差分测量和双频载波相位差分测量相结合靶场高精度脱靶量测量方案。在对靶场现有GPS脱靶量测量技术分析的基础上,设计了高精度的脱靶量测量原理图,并对其可行性进行仿真分析。仿真结果证明:该方法有效地提高了脱靶量测量精度,满足靶场高精度飞行器试验的测量要求。

Design and Simulation Realization of High Precision Miss Distance Measurement in Range

Aiming at the limit application condition of aircraft system miss distance measurement which can not meet the test requirement, put forwards a range high precision miss distance measurement scheme by combining dual-antenna diversity reception, pseudo range difference measurement and dual frequency carrier phase difference measurement. Based on analysis of GPS miss distance measurement technology, design the high precision miss distance measurement schematic diagram, then carry out simulation analysis on feasibility. The simulation results show that the method effectively improve miss distance measurement precision, satisfy the measurement requirement of high precision aircraft test in range.
