Abstract

Based on the general model of signals scattered by the rough surface of the seabed, relations are developed for estimating the errors of measurement by the interferometric side-scan sonar (ISSS) of the arrival angles of echo signals caused by the decorrelation of the probing signals with a large base in the receiving channels due to the spatial separation of the antennas. The obtained relations allow us to adjust the signal processing algorithms received by the multiantenna interferometer to reduce the influence of additive noise on the accuracy of the measurements of the angles of arrival of echo signals.

解相关因子对干涉系统测量信号相位差的误差的影响

摘要

基于在海床粗糙表面上散射的信号的一般模型，建立了关系式，以估计由探测信号的去相关引起的回波信号的到达角的干涉式侧面扫描声纳（ISSS）的测量误差由于天线的空间分隔，在接收通道中具有较大的基数。所获得的关系使我们能够调整多天线干涉仪接收到的信号处理算法，以减少附加噪声对回波信号到达角测量精度的影响。
