Abstract

The invention is suitable for the technical field of millimeter wave radar, and provides a target detection method and a target detection device, and the method comprises the steps: obtaining at least two frames of echo signals, and the at least two frames of echo signals comprise a first echo signal and a second echo signal; determining motion information of the target object according to the first echo signal; determining a first set according to the motion information and the first echo signal; determining a second set according to the motion information and the second echo signal; performing combination processing on the first set and the second set to obtain a target echo signal; determining the target object according to the target echo signal; and outputting distance information and / or speed information according to the target object. According to the scheme of the invention, the effective data related to the target object in the at least two frames of echo signals are processed, so that the detection precision of the target object can be improved.

Description

technical field [0001] The present application belongs to the technical field of millimeter wave radar, and in particular relates to a target detection method and a target detection device. Background technique [0002] Accurate object detection has important applications in the driving domain. For example, in the traffic intersection scene, the uneven distribution of traffic flow on different roads can be effectively avoided through the target detection technology; in the parking toll road section, the lane congestion can be avoided through the target detection technology. [0003] At present, radar equipment is usually used to send frequency-modulated continuous wave signals, and the target object is detected through the echo information received by the radar equipment and reflected by the target object to the radar equipment; however, due to the complex traffic environment, there are many vehicles and other traffic participants, There is a problem that the information re...
