摘　　要：动态目标测量是雷达目标RCS特性研究必不可少的一种手段。简要介绍了RCS特性测量数据分析方法,设计了某型直升机动态飞行测量实验,分析了目标航迹数据、姿态角数据和RCS测量值,应用χ2分布模型拟合目标在2.5GHz测量频率水平极化和垂直极化两种方式下RCS测量数据的统计特征,并分析该目标RCS的起伏规律。The dynamic target measure is absolutely necessary in the research of radar target RCS. The analyzing method of measured data of RCS performance is briefly introduced,and the dynamic flying measuring experiment of a helicopter is designed. The flying track data measured in the test, the data of gesture angle and the measuring value of RCS from the actual measuring target are analyzed. The statistical distributing characters of the characterized measuring data tested under the polarizing situation of the measuring frequency level of 2.5 GHz and vertical polarization respectively in X^2 distribution simulating combination target are applied. The undulating law of the target RCS is also analyzed.
