为了提高多目标跟踪的精度和跟踪系统的鲁棒性,提出雷达-红外分布式融合多目标跟踪算法。在直角坐标和修正球坐标相结合的混合坐标系运用GM-PHD滤波实现雷达多目标跟踪,解决因坐标变换引起的非线性问题和量测噪声耦合问题。在修正球坐标系中运用GM-PHD滤波,实现红外传感器的多目标纯角度跟踪。将红外角度估计与雷达状态预测在融合中心进行数据融合,提高跟踪精度。计算机仿真验证表明,雷达和红外传感器可以单独实现多目标跟踪,融合后具有更高的跟踪精度。
Abstract：In order to improve the accuracy of multi-target tracking and the robustness of tracking system,a multi-target tracking algorithm based on radar-infrared distributed fusion is proposed.In a hybrid coordinate system composed of rectangular coordinates and the modified spherical coordinates,a GM-PHD filter is used to realize radar multi-target tracking to solve the nonlinear problem and the problem of measurement noise coupling caused by coordinate transformation.A GM-PHD filter is used in the modified spherical coordinates to achieve multi-target pure angle tracking with infrared sensors.The infrared angle estimation and radar state prediction are fused in the fusion center to improve the tracking accuracy.The computer simulation shows that the radar and infrared sensors can realize multi-target tracking separately,and higher tracking accuracy can be achieved after fusion.
