基于动态RCS的机动目标探测概率计算方法

The Detection Probability Calculation of Moving Targets Dynamic RCS

针对机动目标探测研究中对目标雷达散射截面(RCS)使用的局限,提出了借助动态RCS电磁计算进行机动目标探测概率计算的方法。该方法通过RCS与回波幅度的关系纽带,建立了考虑目标特性的探测概率计算模型,相较于传统起伏模型的直接应用更具合理性。仿真结果表明,机动目标的探测受到距离和目标特性共同作用,当距离在一定范围内时探测概率还会出现明显起伏。该研究有助于更加全面地研究机动目标探测机理,为攻防两方如何利用目标特性提升装备性能给出了直观参照。

Aiming at the limitation of the RCS(radar cross section)application in detection on moving targets,a method of detection probability calculation based on dynamic RCS was proposed.Firstly,the dynamic RCS data was calculated.Then a detection probability calculation model considering target characteristics was set up according to the link between RCS and radar echo.Finally,the real-time detection probability under two typical tracks ws simulated by use of the dynamic RCS gained.The experiment result showed the detection probability varied with distance and target characteristics and fluctuates when distance was within certain value.The method could offer a more profound understanding on the detection of moving targets and gave an intuitive reference on how to improve performance with target characteristic on both ends.
