摘要

<FONT face=Verdana><FONT face=Verdana>提出建立累积和检验算法的反馈机制。从匹配滤波器平方输出端信噪比序列的估算、归一化处理和门限的求取几方面研究了算法和信息反馈流程，分析了信噪比失配对检测性能的影响以及门限信噪比设置对虚警性能的影响。海试数据验证结果表明声场预报加结果反馈机制的应用使得累积和算法在处理低频低信噪比信号的性能上有显著提高，算法性能优于常规时空背景均衡处理结果。

Abstract

<FONT face=Verdana>A feedback mechanism of the Page Test is proposed to establish. From the aspects of the estimation of SNR on square output of the matched filter

normalization

and the gate calculation

the algorithm and information feedback flow are researched. We also study the effect of SNR mismatch on the detection performance and the effect of gate-SNR design on the false alarm performance. The experiment on the sea shows that the performance of the Page Test with sound field prediction and feedback mechanism is improved evidently when processing lower frequency signals with lower SNR

and its performance is better than the conventional space-time background equalization algorithm.
