红外传感器有着良好的测角性能，激光传感器则有良好的测距、测角性能.将两者联合起来跟踪目标可以发挥各自的优势.提出一种红外传感器和激光传感器联合探测的模型.将各自测得的信息进行时间配准和数据融合后，用α-β滤波器对目标进行滤波跟踪，仿真结果表明可以得到较好效果.

Infrared sensor is good at measuring angle while laser sensor is good at measuring distance and angle. Combing the two sensors can exert their predominance each other. A detection model of combining the infrared and laser sensors is put forward. After timely matching the information measured by every sensor and fusing the data, the targets are being tracked by α-β filter, the simulation results show that the method is feasible and satisfying.
