Abstract

The invention is suitable for the technical field of radars, and particularly relates to a multi-radar fusion false target suppression method and device and terminal equipment, and the method comprises the steps: obtaining radar targets detected by a plurality of radars on a target device in a current period and the attribute value of each radar target; according to the position information of each radar target in the current period and the range of a fusion region around the target device, taking the radar target in the fusion region as a first radar target; based on the similarity between each first radar target in the current period and each fusion target in the previous period, determining a fusion attribute value of each fusion target in the current period; and according to the fusion attribute value of each fusion target in the current period, calculating the false probability of each fusion target in the current period, and deleting the fusion target of which the false probability in the current period is greater than a preset probability threshold. According to the scheme, false targets detected by the radar can be effectively suppressed, and the radar detection accuracy is improved.

Description

technical field [0001] The invention belongs to the field of radar technology, and in particular relates to a false target suppression method, device and terminal equipment for multi-radar fusion. Background technique [0002] Millimeter wave radar is a radar that works in the millimeter wave band (millimeter wave). Because of its advantages such as long detection distance, high resolution, speed measurement and all-weather use, millimeter wave radar is widely used in the field of assisted driving and intelligent driving. [0003] When the millimeter-wave radar is working, due to the multiple reflections of the electromagnetic waves in the environment, the radar detects some false targets, that is, multi-path targets, and when the radar receives the electromagnetic waves emitted by other devices and performs signal processing such as demodulation , some interfering targets will be detected, and these false targets will lead to wrong decision-making of vehicle functional saf...
