角跟踪法实现相差率测量单站定位

Angle Tracking Single Station Emitter Location via Phase-Difference-Rate Measurement

在介绍了目前诸多单站定位方法后，探讨了干涉仪相差率测量条件下采用角跟踪方法实现辐射源单站定位的原理、方法，并结合测量误差的实际．通过EKF仿真证明该方法实现的收敛速度和误差容限都较好，最后总结了工程实施中可能需要注意的问题。

This paper introduces single station location methods used currently. Then discusses the principle and means of passive single station emitter location by angle tracking based on the phase difference rate measurement of two elements interferometer. According to the engineering practice related to this equipment, we simulate the location process using tracking filter EKF to testify the feasibility of this method, including its disadvantages and problems.
