反导作战中雷达和ESM辅助关联的仿真研究

水面舰艇反导作战中对来袭导弹进行目标指示,首先要进行航迹关联,可以利用ESM和雷达的方位信息进行关联。但仅仅利用方位这个单一信息进行关联,依据的信息有限,关联概率不够精确。通过ESM获取的导弹目标末制导雷达信号幅度数据与导弹目标距离的比例函数关系,在方位关联的基础上,利用导弹末制导雷达信号幅度大小与导弹目标距离大小进行辅助关联。仿真结果表明,关联概率显著提高,证明了辅助关联的有效性与实用性,对水面舰艇在反导作战中进行目标跟踪和识别具有重要作用。

Simulation research on radar-ESM assistant correlation in the anti-missle combat

Naval vessels have to make a track relating based on the bearing of ESM and fire control radar before making a target track and identify in the guard against air and anti-missle.But the relating probability is not high enough because of the limited information.The article puts forward a new way,which makes use of the proportion between the signal range obtained by the ESM and the target obtained by the radar,making a assistant correlation between the signal range and the distance,then makes a emulation,which shows that the correlation probability improved remarkably,also validates the validity and practicability of the assistant correlation.which has an important function in a target track and identify.
