摘要
提出了一种基于方位和线谱频移序列的目标运动分析新算法,解决了方位序列估计器工作点漂移方法中初始方位漂移角度较难确定的问题;提出了一种新的多普勒频移匹配估计器,不需要预先提取目标线谱即可估计目标运动参数,并且有效地加快了目标运动参数解算的收敛速度。海上实验数据处理结果表明该算法较以往同类算法在收敛速度和解算精度等性能上有明显改进。
Introduce a new TMA based on bearings and line doppler shift. This method can resolve the difficult problem of determining the original drifted angle in working-point drifting method; a new matched doppler shift estimation is introduced, it can estimate the movement parameter without extracting the line spectrum of target and the convergence speed of the target movement parameter is more faster. Then, the better performance of the new TMA in the convergence speed,solution precision, and so on, is testified by the processing of experimental data on the sea.
