摘　　要：空中目标的RCS建模是雷达系统建模中的基本问题,面向作战分析仿真的RCS建模需要较高的模型精细度和运算可操作性。RCS的统计特征会随着姿态角、频率、极化方式以及观测时间而变化,所以目标RCS的统计特征除了特殊情况外,是不实用的。因为通过对空中目标形态的分析,提出了空中对称目标和旋转目标的RCS建模方法,给出了该方法的插值运算形式,最后探讨了仿真运行中目标RCS的运行流程。Modeling technique of aerial target RCS is a difficulty problem in the task of radar system modeling.The model of special detail and calculable operation is required in the RCS modeling that based on fighting analysis simulation.A valid concern is how to model real target behavior so that radar performance can be predicted from the radar range equation.If the statistics of the target＇s cross section can be determined or assumed,application of the classical theory of detection of signals in noise can provide the required signal-to-noise ratio as a function of the probabilities of detection and false alarm,and the number of pulses integrated.It is difficult because the cross-section statistics can vary with aspect,duration of observation,and frequency.Based on the analysis of aerial target shape,modeling technique of aerial symmetrical and roll target RCS is proposed.A method of compute is included in the paper.At last,an operation flow of target RCS in simulation is presented.
