针对复杂电磁环境下海上无人平台前出抵近电子侦察的场景，提出一种干扰条件下针对机动目标的多平台协同纯方位无源定位方法。该方法首先建立干扰条件下的伪量测线性方程，然后通过衰减记忆滤波解算无源定位模型获得机动目标实时位置，并在计算过程中引入平方根算法以提高算法的稳定性，最后对多平台无源定位结果进行补偿校正，从而进一步减少定位结果与真实值的偏差。仿真分析结果表明，该算法相较传统方法具有更高的精度。
Aiming at the scenario of forward electronic reconnaissance of marine platforms in complex electromagnetic environments, this paper proposes a multiplatform collaborative bearing-only passive localization method for maneuvering targets under interference conditions. First, this method establishes a pseudo measurement linear eqution, and then solves the passive localization model through fading-memory filtering to obtain the real-time position of the maneuvering target. The square root algorithm is introduced in the calculation process to improve stability of algorithm. Finally, the passive positioning results of mutilple platforms are compensated and corrected to reduce the deviation between the positioning results and the true values. The simulation analysis results show that this algorithm has better accuracy than traditional methods for maritime maneuvering targets.
