针对地面防空预警雷达探测效能实验验证问题,将目标发现概率解析计算和雷达功能仿真相结合,构建了较完整和完备的雷达探测概率仿真模型.该模型包括视距判断、信噪比求解、干扰功率计算等模块和仿真环节,能够基于典型飞机目标的航迹想定,仿真计算单部雷达和雷达网对目标所有航迹点的综合探测发现概率,可为地面防空预警雷达装备探测效能仿真验证和作战使用研究等提供支持.最后,通过不同层次和粒度的仿真实验,验证了模型的有效性和可行性.

With full consideration of the problems of testing the detection effectiveness of ground air defense early-warning radar by experiments, this paper sets up a more complete simulation model for the probability of radar detection by combining the analytic computation of target discovering probability with the simulation of radar functions. This model includes the modules of estimation of visibility range, solution of SNR, calculation of jamming power and etc., as well as some simulation links. And this model can be based on the typical aircraft targets＇ track cenarios to simulate and compute the single radar and/or radar network＇s integrated detection probability of targets＇ all track points, thus providing the technical support for simulation test of the detection effectiveness of ground air defense early-warning radar equipment and the study of operational use. Finally, it is effectively proved that this proposed model is of availability by performing the simulation experiments on multi- levels and granularity.
