摘　　要：针对典型的已知巡航速度范围的运动辐射源,提出了一种基于速度先验的单平台快速无源定位方法,利用单平台测得的辐射源方向信息,结合先验速度信息,实现对运动目标的单平台快速无源定位,此方法改善了地面固定单站对运动辐射源的定位可观测性,且定位解算速度较快,对运动辐射源的运动形态没有明显要求。最后,通过计算机仿真,验证了算法的有效性。Aiming at typical moving radiation sources with known cruising velocity scope,this paper proposes a single-platform fast passive location method based on prior velocity.In this method,the DOA information of radiation source measured by single platform and prior velocity information are used to perform the single-platform fast passive location for moving target.This method can not only improve the observability of moving radiation source location based on fixed ground single station,but also have higher location solving speed.At the same time,this solution has no more requirements for the motion form.At last,The computer simulation results show that the proposed method is available.
