摘要

为了解决双基地声呐系统定位误差的存在严重制约性能提升问题，本文研究其误差统计特性，利用蒙特卡罗方法验证了基于误差函数的置信椭圆是一种有效的误差分析方法，并仿真分析时延误差、接收阵测向误差以及收发节点位置误差等主要误差源对多基地定位性能的影响。结果表明：时延和测向误差对定位精度影响显著，收发节点位置误差影响较小；分置距离超出特定阈值时定位误差显著增加，目标靠近发射节点特定接收角度时误差较大。本文分析结果可为系统定位精度分析及工程应用提供参考。

Abstract

Localization errors severely constrain enhancing the performance of bistatic sonar systems. To address this problem

this study investigated the statistical characteristics of these errors using Monte Carlo simulations

confirming that the confidence ellipse based on the error function is effective for error analysis. Through simulations

the impact of major error sources

including time-delay errors

receiving array bearing measurement errors

and transceiver node position errors

on the multistatic localization performance was further analyzed. The results indicate that: 1) Time-delay and bearing measurement errors significantly affect the localization accuracy

whereas the transceiver position errors have a minimal impact; 2) localization errors will increase substantially when the separation distance exceeds a specific threshold; 3) larger errors will occur when targets approach specific receiving angles relative to the transmitting node. These findings provide critical references for the analysis of the system accuracy and engineering applications.
