摘要

定向声纳阵列中水听器的输出信号在进一步处理之前经常被截断。本文通过比较在裁剪数据和未裁剪数据上工作的似然比检测器的优劣值，分析了这种影响。结果表明，如果水听器的数量较多，其优值将比最优值降低约2/π。

Part II: Degradation of Detectability Due to Clipping

The output signals from the hydrophones in a directional sonar array are frequently clipped before being processed further. The effect of this is analyzed in this paper by comparing the figures of merit of likelihood-ratio detectors operating on clipped and unclipped data. It is found that if the number of hydrophones is large, the figure of merit is reduced by a factor of about 2/π from the optimum value.
