摘要

提出了一种基于恒虚警率(CFAR)技术的声纳检测方案。该系统具有以下优点:该方法在非均匀水下环境下产生无偏估计，因为在存在干扰目标的不同水下环境下，虚警率保持在一个恒定的水平，而阈值会发生变化。还对不同的CFAR处理器进行了数学分析，并对CFAR损失感兴趣。使用平均决策阈值(ADT)作为度量。

Sonar based automatic target detection scheme for underwater environments using CFAR techniques: a comparative study

A sonar detection scheme is presented using Constant False Alarm Rate (CFAR) techniques. The proposed system has the following advantage. The technique yields unbiased estimates under a non-homogenous underwater environment, because the false alarm rate is maintained at a constant level while the threshold changes with different underwater environments in the presence of interfering targets. A mathematical analysis is also being done for different CFAR processors with the interest on the CFAR losses. Average decision threshold (ADT) is used as a measure.
