摘要
研究了互相关法在无源时差定位系统中的应用。对于单站侦收的微弱副瓣信号,不需要测量其参数,利用互相关法即可提取时差信息;对于受强噪声和干扰信号污染的目标信号,利用互相关法将其分选出来并测量时差。仿真研究了频率、重频、脉宽对两个信号的互相关输出增益的影响。
Cross-correlation in passive TDOA locating is discussed. The feeble sidelobe signal reconnoitred by single station can obtain TDOA using cross-correlation instead of measuring parameters, and the target signal jammed by strong noise and other signals can be sorted using cross-correlation, then TDOA is measured. The cross-correlation output enhancement of two signals with different frequencies, PRFs and PWs are simulated.
