Airborne Radar Tracking Method Research and Simulation

研究机载雷达跟踪运动物体的准确性问题。针对当物体运动的速度较快时,在机载雷达跟踪过程中需要完成光机扫描、图像合成、图像处理、信息传输等一系列综合处理过程,产生时间滞后,一旦被跟踪的物体运动速度较大,两者速度不匹配,就会造成跟踪高速运动目标识别不准确的问题。为了解决上述问题,提出基于滞后时间补偿的机载雷达跟踪方法。通过建立被跟踪的目标的运动模型,估计出跟踪物体下一刻运动位置,提前消除时间滞后,克服传统方法的缺点。实验结果表明,运用改进方法可以很好的消除时间上的滞后延迟,完成机载雷达对高速运动物体的跟踪,大幅提高跟踪的准确性。

Research the accuracy of the airborne radar tracking the moving objects.The traditional airborne radar tracking method needs to complete a series of comprehensive treatment process,such as light machine scanning,images synthesis,image processing,and information transmission.When the object motion is fast,the time lags occure,causing inaccurate problem of tracking high-speed moving targets.In order to solve this problem,the airborne radar tracking method was put forward based on the time lag compensation.Through the establishing the tracking model of the target,the tracked object was estimated for the next position,eliminating the time lag in advance and overcoming the disadvantages of traditional methods.The simulation experiment shows that the method can be used to eliminate the time lag and increase the tracking accuracy.
