On Feedback Mechanism of the Page Test
Zhiming Cai · Dianzi xuebao · 2010
A feedback mechanism of the page test is proposed.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.
