导弹遥控过程的CADET算法精度分析

摘要

协方差分析描述函数法(CADET)首次用于导弹遥控过程的精度分析.该方法通过将导弹的非线性误差、导弹的加速度计误差、以及机载雷达的目标探测误差引入导弹的中制导方程,得到CADET算法模型和误差模型,并对各项误差进行仿真.结果表明,将CADET算法引入导弹的遥控过程,能有效分析各个误差对遥控精度的影响.%Covariance Analysis Describing function Technique (CADET) algorithm was used to analyze the precision of missile's remote control process. The nonlinear error of the missile, the accelerometer error of the missile, and the target detection error of airborne radar were introduced into the equation of the midcourse guidance. Then the CADET algorithm model and error model were obtained. Simulations were made for the different errors. The results show that the effect of each error on precision of remote control can be analyzed effectively by introducing CADET algorithm in remote control of the missile.
