摘　　要：多站纯方位交汇定位技术是分布式被动传感器协同探测问题的重要基础。针对传统三角形交汇定位法中忽略测角偏差而导致的测量精度不高的问题,提出基于三角定位模型的两条方位线交汇中心偏离真值问题,给出偏差计算数学模型,推导建立去偏三角形定位方法,提出双站和三站被动探测和定位系统的偏差生成和去偏方法,实验结果表明,生成的含有测角偏差的数据与实际测量规律一致,构建的去偏三角定位方法比传统纯方位定位法定位精度更高,该算法可以为高精度分布式多站纯方位探测和定位提供有效手段。Multi-station beaninps-only intersection localization techniques are an important foundation for the problem of cooperative detection of distributed passive sensors.This article addresses the issue of low measurement accuracy caused by neglecting angle measurement devia-tion in traditional triangle intersection positioning methods.This is the first time that the problem of deviation from the true value of the intersection center of two azimuthal lines has been proposed based on a triangle localization model.A mathematical model for deviation calculation is derived,and a deviation-removal triangular location method is established.Deviation generation and deviation-removal methods for passive detection and positioning systems with dual and three sta-tions are proposed.The experimental results show that the generated data with angular measure-ment deviation is consistent with the actual measurement method.The constructed deviation-removal triangulation method achieves higher localization accuracy than the conventional bearing-only method.This algorithm can provide an effective means for high-precision distributed multi-station bearing-only detection and localization.
