摘要
主要应用精度统计分析的协方差分析描述函数技术,对改进的比例导引律制导精度进行研究。首先介绍了协方差分析的原理,然后对高斯假设的有关结论及合理性进行了分析。再用该方法对改进的比例导引律进行精度分析。仿真结果表明,这种改进的比例导引律导引精度有很大提高。
The covariance analysis describing function technique （CADET） , which is used for the improvement of proportional guidance law, is studied. Firstly, the principle of this method is introduced. Then the related conclusion and validation of Gaussian assumption is analyzed. Secondly, an improved augmented proportional navigation guidance law （APNG） is analyzed with this method. Finally, the higher guidance accuracy of this improved APNG is demonstrated by stimulated experiments
