多路径对无源雷达时差信号测量的影响
Effect of Multi-path on TDOA of the Passive Radar
摘要
Abstract
To fight against the complex electromagnetic circumstance,increasing attention has been attached to passive radar for its advantages in principle and constitution.As an important branch of passive radar,long baseline time difference of arrival(TDOA) locating radar uses several measurements of TDOA to locate the spatial radiation source.Due to the direct wave and the reflected wave of a radiation source enter the receiving antenna of the passive radar,the amplitude and phase of the received signals will be changed,which will result in the measurement errors of TDOA and deteriorate positioning accuracy.This paper offers a model description and theoretical analysis of the multi-path of passive radar,and also provides the detailed deduction and simulation for its effects on the measurements of TDOA.关键词
