基于回波空间特性的潜艇目标识别研究

本文阐述了基于波束分裂的互谱法定向理论,给出了水下体目标的亮点模型.在此基础上,提出了一种利用体目标回波的空间方位分布信息识别水下目标的方法.通过对亮点模型目标回波的方位角和俯仰角进行估计,估算出目标的线性尺度,实现体目标的识别,最后通过计算机仿真给出了估计量的估计方差并进行了相应的分析.

Submarine Target Identification Based on Echo Features in Space Domain

This article expatiates a cross spectrum directional theory based on split beam and studies a highlight model of a underwater target.The method reckons the linear dimensions of the target and recognizes the target by means of estimating target reverberation azimuth angle and elevation angle of the highlight model.Finally,variance estimate is given out by computer simulation and is analyzed,which proves that the highlight model of a underwater tartget can meet the requirement of target dimension recognition.
