摘要
基于卫星在不同位置测得的信号相位差,提出了一种用最小二乘使误差最小化的单星无源定位方法。给出了定位和去模糊的原理与计算方法,以及数学模型,建立了定位误差的解析表达式,用仿真验证了误差表达式。结果表明该法有一定的去模糊定位和单基线测量相位差定位能力。
A method of passive emitter-location for single satellite with minimizing phase difference error by least square method based on phase difference error of signals measured at different positions was put forward in this paper. The principle, computation method and algorithm of location and de-ambiguity were given. The analytic expression of location error was deduced. The accurate of the error expression was approved by simulation. The analysis results showed that this method had ability of unambiguous location and location with measurements by single base line.
