Abstract
: It takes a long time to detect target information in noisy radar information and reduce the probability of false alarm. Therefore, it has become a research direction to reduce the probability of false alarm and the time of effective target detection. This paper introduces a new method to reduce the occurrence of false alarm in non-uniform environment and improve the efficiency of target detection. The proposed method involves a faster and more stable method that involves preprocessing the data set, splitting it into smaller parts, and utilizing a KTH minimum value M determined by an ordered statistics class constant false alarm detection algorithm. Each data point in the small segment is then compared to M , anything above M is classified as a target, and anything below M is ignored as clutter. Then ESVI-CFAR detection was performed on the selected target to obtain the final detection result. Experimental results show that the proposed method is superior to the traditional VI-CFAR and has better target detection performance.
:在噪声雷达信息中探测目标信息并降低误报概率需要很长时间。因此,降低误报概率和有效检测目标的时间成为研究方向。本文介绍了一种在非均匀环境下减少误报发生、提高目标检测效率的新方法。所提出的方法涉及一种更快、更稳定的方法,即对数据集进行预处理,将其分割成更小的部分,并利用有序统计类恒定误报检测算法确定的 KTH 最小值 M。然后将小部分中的每个数据点与 M 进行比较,高于 M 的数据点被归类为目标,低于 M 的数据点被忽略为杂波。然后对选定的目标进行 ESVI-CFAR 检测,得到最终的检测结果。实验结果表明,所提出的方法优于传统的 VI-CFAR,具有更好的目标检测性能。
