摘　　要：在前人研究基础上,针对高速运动辐射源目标,提出了更具鲁棒性的基于机载单站双航段联合估计的纯方位目标定位跟踪算法。该算法通过机载单站的两个不同航段飞行,一次性完成对匀速直线运动目标的距离、切向速度和径向速度的估计,且在求解过程中没有加入任何强制性的约束。在典型场景的仿真实验结果验证了新提出算法的有效性。On the basis of previous research, a passive bearing-only target location and tracking algorithm based on joint estimation with two flight segments of the single observer is proposed for locating the dynamic emitter. Based on the proposed algorithm, the single observer, moving in different flight courses, can evaluate the position and velocity of the emitter without restrictions. Experimental results in the representative scene demonstrat the effectiveness of our approach.
