| 摘 要： | 为研究存在视线角速度测量噪声时非线性比例微分(PD)型比例制导方案的鲁棒性,以近距大离轴角发射和目标大机动为拦截条件,对四种视线角速度测量噪声方差进行蒙特卡罗仿真模拟。结果表明,非线性PD型比例制导方案抗视线角速度测量噪声的鲁棒性强,对机动目标拦截制导精度高,是一种具工程应用价值的高精度末制导方案。

| Abstract: | To study the robustness of nonlinear PD-type proportional navigation guidance when the measurement noise of LOS-rate existed,the Monte Carole simulation for four different variance of measurement noise for LOS-rate was made under the conditions of short distance and big off-axis angle launch and high g maneuvering of target in this paper.The research results showed that nonlinear PD-type proportional navigation guidance not only had superior robustness to LOS-rate measurement noise,but also possessed higher guidance accuracy than PN when used in intercepting high-g maneuvering targets.The nonlinear PD-type proportional navigation guidance was very hopeful to be implemented in high performance terminal guidance systems. |
