基于运动学原理的单站无源定位改进算法

传统的单站无源定位方法主要是测向三角定位方法,但由于该方法对测角精度的敏感性,仅利用DOA信息会导致定位精度较低。提出了一种利用相位变化率和多普勒频率变化率信息的单站无源定位方法。分析了此定位算法在单次测量定位时的精度和可观测性,最后给出了在单次测量定位时的计算机仿真结果和结论。

Passive Location Method of Single-Point Based on Kinematic Passive Range Detection

In traditional passive location methods, the cross of direction lines by the useof DOA direction of arrivalinformation is a main method. But the method may lead to worse accuracy or slower convergence because of the sensitivity for DOA. One method is presented which adopted PRC Phase Rate of Changeand DFRCDoppler Frequency Rate of Changeinformation. Analysis of the location precision and observability of the method is discussed. In the end, the paper gives computer emulation of single measurement and a conclusion.
