| 摘 要： | 从装备面临的实际战场情况出发,在分析时差定位原理和雷达诱偏合成信号特性的基础上,分析了时差定位系统在存在诱偏信号情况下的侦收信号情况,对相关处理后的时差输出进行了建模和仿真研究,并分析了诱偏信号对时差定位系统精度的影响原因。针对三站时差定位系统和三点源诱偏系统,对典型态势下由诱偏信号引入的定位误差进行了仿真计算,得到了诱偏信号引入的误差分布情况和规律。

| Abstract: | Based on battlefield actuality confronting equipment and following study of TDOA (Time Difference of Arrival) location principle and characteristics of radar decoy synthesized signal, this paper analyzes the signal reconnaissance status with decoy signal condition of TDOA location system.Modeling and simulation were done on TDOA output by correlation processing and causality of decoy signal influence on TDOA location system precision was analyzed.For three station TDOA location system and three decoy system, simulation and computing were performed on location error caused by decoy signals under classical situation, and the distribution situation and regularity of leading error were acquired. |
