摘要
Abstract
Due to the large number of navigation satellites and a lot of choices,the selection of satellite termed as illuminators of opportunity(IoO)becomes a key factor limiting the positioning accuracy of passive radar.A multi-satellite and single-receiver positioning model based on passive radar using navigation satellite as IoO is established,the number and position of visible navigation satellites are calculated,the system positioning error equation is derived,the positioning error influencing factors are analyzed,a geometrical dilution of precision(GDOP)based optimization method of IoO for time difference of arrival(TDOA)location of multi-satellite and single-receiver passive radar is proposed.The simulation results show that the method can reliably screen the best IoO for multi-satellite and single-receiver TDOA positioning,and can effectively improve the positioning accuracy of the system.关键词
