摘要
现代战场处于复杂的电磁对抗环境之中,在空袭与防空作战中,制电磁权的斗争集中表现在雷达领域,防空雷达的探测模型是防空作战仿真中不可或缺的重要模型。传统的雷达模型对复杂电磁环境考虑的不够,模型通常为距离模型而非概率模型,并且模型参数过于复杂,不适合大规模作战仿真的需要。针对复杂电磁环境下电子对抗和雷达装备的特点,在雷达距离方程的基础上,对雷达探测的某些问题做了合理的简化,参考雷达探测的BLAKE图解法,采用功能性仿真,计算统计意义上的雷达探测概率,建立了雷达探测的概率模型和仿真算法。通过仿真结果与相关型号试验数据的印证,表明模型能够确切反映相关雷达的真实作战效能,适合作战仿真的需要。
Today the battlefield is often in a complex electromagnetic environment, so radar＇s detection model is a key model for the air defence operation simulation. Traditional model gives few or no consideration to the complex electromagnetic environment, which is a distance model rather than a probability model. This kind of model with too many parameters is unsuitable for the large scale operation simulation. In view of the characteristics of ECM and radar equipments, some issues are simplified based on radar distance equation. By using BLAKE Chart Method as a reference, statistics - based radar detection probability is calculated with functional simulation method. With all these efforts, mathematical model and simulation arithmetic are given. Simulation results are verified by correlated radar test data, which indicate that this model is able to describe the real efficiency of correlated radar and is applicable for operation simulation.
