摘　　要：首先定义并给出了求取隐身目标的方位角、航向角和方向角的计算公式;然后拟合求取目标的雷达散射截面积(RCS)并近似计算隐身目标在不同频段雷达下的检测概率Pd,给出了组网雷达探测跟踪隐身目标的结构框图及流程图;最后进行了仿真验证与分析。结果说明了在间断检测到隐身目标的情况下,采取的滤波处理方式能较好地探测并跟踪隐身目标。Firstly the calculation formula for obtaining the azimuth angle,heading angle and direction angle of stealthy tar-get is defined and given. Then the target RCS is calculated and the detection probability Pd of stealthy target in different frequen-cy bands is also calculated approximately. The structure diagram and the flow chart of networking radar detecting and tracking stealth targets are given. Finally the simulation and analysis is conducted,the results show that,in the condition of discontinu-ous detect stealthy target,the adopted filtering treatment can better detect and track stealthy target.
