在目标航迹断续下雷达和ESM数据关联的新方法

雷达和ESM是获取敌方目标电子信息最重要的传感器,通过航迹关联、估计处理,可以提高对空域的态势感知能力.当雷达和ESM的探测目标航迹处于断续情况下,角度直接关联的不确定性很容易造成错误关联或漏关联,从而不断起始新的融合航迹.论文将测量的角度转换为证据,再利用DS理论进行频谱、属性等证据综合推理,能较好地提高关联正确率,维持融合航迹的连续性.

New Method of Radar and ESM Correlation When Track Broke

The radar and ESM are the most important sensors to get electronic information of enemy target. According to track association and estimation, they can improve situational awareness of airspace. When target track is broke, leak probability and false probability of association by angle are increased, and the fusion track number is increased too. Through converting the measurement to evidence; D-S theory can improve correct percent of track association and track continuity by evidence of measurement, attribute and frequency.
