【摘要】T raditional single station passive location algorithm based on phase difference rate of change uses the direction and phase-difference rate of change as the observation quantity to estab-lish observation equation ,and calculates the target position by means of location filtering algorithm recursion .Due to the effects of receiver channel amplitude/phase errors and platform attitude error of direction finding system ,it is difficult to realize high-accuracy direction finding ,w hich will effect the localization precision and convergence speed .Because the direction and phase-difference rate of change parameters are got through independent antenna array measurement ,this paper brings for-ward to get rid of direction finding antenna array ,uses two antenna units to extract phase-differ-ence rate of change ,and estimate the target location only by taking phase difference rate of change as the observation quantity .The location algorithm can reduce the number of system hardware effi-ciently and simplify the location operation course as well as improve the location operation speed .%传统相位差变化率单站无源定位技术是以方位和相位差变化率为观测量，建立观测方程，通过定位滤波算法递推计算出目标位置，由于测向系统受接收机通道幅相不一致性、平台
