并线工况下车载雷达有效目标快速检测方法

为了改善车载雷达在前车切入工况下同车道目标检测的实时性,在前方目标有效性检测方法的基础上,提出针对此种工况的目标快速检测方法.采用Kalman预测作为目标有效性判断准则,并引入有效概率表征目标有效性;在此基础上,通过扩大目标搜索范围,建立有效概率继承机制,提高前车并线工况下目标检测速度.实验结果表明,快速检测方法在有效排除路旁干扰物和虚假目标的影响以及鲁棒检测目标的同时,提高了前车并线工况下目标检测的实时性.

Method of Rapid Detecting Cut-In Target By Vehicular Radar

A rapid detecting method based on target validity was proposed to improve detecting performance of cut-in target using vehicular radar.The Kalman prediction was used as the judgment criterion of target’s validity which could be represented by valid probability.In consequence,by extending the searching range to sidelines and setting up an inheritance mechanism of valid probability,the detection rate of the cut-in target was quickened.The experiment results show that the proposed rapid detecting method is robust and it can remove the disturbance caused by roadside objects or false signals.Moreover,the real-time performance of detecting cut-in target is improved obviously.
