Matched Field Processing Based on the Least SquaresAlgorithm for Short Vertical Linear Array

摘要

摘要: 匹配場(chǎng)處理通常要求接收基陣能夠覆蓋整個(gè)水層，如此大尺度的布陣方式嚴(yán)重阻礙了該方法的廣泛使用。為了緩解匹配場(chǎng)處理對(duì)陣形的苛刻要求，該文提出一種基于最小二乘的短垂線陣匹配場(chǎng)處理技術(shù)。該方法把接收陣的聲場(chǎng)分解為模態(tài)函數(shù)矩陣和模態(tài)系數(shù)向量，并在最小范數(shù)意義下用最小二乘算法得到了各階模態(tài)系數(shù)的估計(jì)值，在此基礎(chǔ)上重新構(gòu)造了短垂線陣的測(cè)量場(chǎng)向量，使得重構(gòu)后的測(cè)量場(chǎng)包含更多的環(huán)境信息，從而提高了短垂線陣匹配場(chǎng)處理的性能。最后，在典型的Pekeris波導(dǎo)環(huán)境中進(jìn)行仿真，以3種布放在水面附近的短垂線陣為例，分析了匹配場(chǎng)被動(dòng)定位的性能，并用廣義余弦量化分析了不同布陣方式對(duì)測(cè)量場(chǎng)的影響。結(jié)果表明：使用最小二乘算法對(duì)短陣的測(cè)量場(chǎng)進(jìn)行聲場(chǎng)重構(gòu)后廣義余弦變大，此時(shí)短垂線陣匹配場(chǎng)處理的定位性能得到改善，驗(yàn)證了該算法的有效性。

Abstract: The receiver array of matched field processing usually needs to cover the whole water column, such a large arrangement of array hinders its application seriously. To overcome this shortcoming, an approach called matched field processing based on least squares algorithm is proposed, which decomposes the received fields into depth function matrixes and amplitudes of normal mode at the beginning. Then all the mode amplitudes are estimated using the least squares in the sense of minimum norm. Next, the amplitudes estimated are used to reconstruct the received fields of the short vertical linear array, which makes the reconstructed ones contain more environmental information, therefore the performance of matched field processing with short array is improved. In the end, lots of simulations with three short vertical arrays which are located near by water surface are processed in the classical Pekeris waveguide, and the performance of matched field passive localization is evaluated. Meanwhile, in order to quantify the influence of different kinds of geometrical arrangements to the received fields, the generalized cosine-squared between two vectors is used. The results show that when the received fields of short array are reconstructed using the least squares, the generalized cosine-squared is larger obviously, finally the performance of matched field passive localization with short array is improved and the proposed algorithm is proved to be effective.
