摘要
Abstract
In the multi-radar and multi-target track matching,due to the sensor system error spreads with the tracking distance,the radar measurement accuracy decreases,and the track matching error is prone to occur.According to the situation,the multi-meter nonlinear fusion model is applied,the erro model best estimation of trajectory(EMBET)method with spline constraint is adopted to self calibrate the radar measurement element system error.The traditional track matching method using Euclidean distance for track motching is replaced by comparing the differences between rader elements with high accurcy,which effectively solves the problem of reasonable threshold setting of multi-radar track matching.The simulation results prove that the algorithm is ef-fectively applicable,which can greatly improve the accuracy of multi-radar and multi-target track matching,and it has great value for the analysis and evaluation of penetration effects such as multi-target airspace distribution and target recognition.关键词
