SUPER RESOLUTION DETECTION METHOD OF MOVING OBJECT BASED ON OPTICAL IMAGE FUSION WITH MMW RADAR

Due to the defects of millimeter wave (MMW) radar in angle resolution, with the increase of detection distance, the ability of radar to distinguish adjacent objects in azimuth direction will be weakened, resulting in the loss and misestimation of objects information. To solve this problem, radar and optical image object detection methods are fused. The information obtained from the optical image data is used to provide a prior information for radar signal processing algorithm, so as to improve the performance of radar object detection system. Based on the simulations and experiments in a variety of multi-object moving scenes, it shows that the fusion method can improve the detection accuracy of the system and restore the spatial location of the objects more accurately than traditional ways.
