联合探测的发现概率问题研究

Study on Problem of Detection Probability for Joint Detection

以要地防空为背景,先后研究了单雷达探测概率模型和单雷达发现概率模型,然后得到多雷达联合探测的发现概率模型,并得到了多雷达联合探测时发现概率与发现距离的关系。通过算例结果分析可知,采用多个雷达进行联合探测,可较大地提高目标的发现距离,特别是对小目标或隐身目标发现距离的提高具有重要的意义。

For the background to air defense,the single radar surveillance probability model and the single radar detection probability model are studied.Then the found multiradar joint detection probability model is goten,and the relationship of detection probability and discovery distance is found.Through analysis of numerical results,combined with multiple radar detection,the distance of finding the target is greatly improved.It has important significance especially for small targets or stealth target.
