摘要
文中在推导分析雷达最小测量误差(随机误差)理论下限(Cramer-Rao界限)的基础上,在仿真计算出2种常用体制弹道测量雷达的参数测量极限精度后,进一步仿真计算出全弹道坐标的极限测量精度,通过对仿真结果分析比较,对上述这2种体制雷达的测量能力、测量精度有了更清晰的认识,为弹道测量雷达设计与应用提供了重要参考依据。
Based on the derivation and analysis of minimum measurement error theoretical limit, ultimate precision of two commonly used radar system is derived. Then, the ultimate precision of the whole trajectory is calculated from the simulated data. By com- parison, the results give a clear understanding of metrical ability and ultimate precision of two radar system, and provide important reference for device design and application of trajectory measurement radar.
