摘要

针对频繁出现于工程实际中的不完全随机有偏量测为背景的火控系统性能的理论研究,建立了不完全随机有偏量测下的离散线性观测系统数学模型,给出了观测系统统计意义下的估计误差方差Cramér-Rao下界(CRLB);根据目标位置、速度与射击诸元间的非线性误差传递关系,利用U-T变换得到不完全随机有偏量测影响下的射击诸元误差方差下界。以某型数字化高炮火控系统为例,仿真结果表明:在给定探测概率和偏差发生率影响下,针对频繁出现于工程实际中的不完全随机有偏量测为背景的火控系统性能的理论研究,建立了不完全随机有偏量测下的离散线性观测系统数学模型,给出了观测系统统计意义下的估计误差方差Cramér-Rao下界(CRLB);根据目标位置、速度与射击诸元间的非线性误差传递关系,利用U-T变换得到不完全随机有偏量测影响下的射击诸元误差方差下界。以某型数字化高炮火控系统为例,仿真结果表明:在给定探测概率和偏差发生率影响下,观测系统在标准航路特征点上的估计性能较无偏完全量测的估计性能下降23.3%,导致火控系统性能下降25%.
