Abstract

A tunnel scene detection method and a millimeter wave radar are provided, the method is applied to the millimeter wave radar, and the millimeter wave radar can be installed on a vehicle and the methodcomprises the following steps: obtaining a stationary target in a preset area; judging whether the vehicle is driven into a tunnel or not according to the clustering area of the stationary target; ifthe vehicle drives into the tunnel, removing a false target in the tunnel according to a preset inhibition condition. The method can reduce the influence of a false target on the credibility of the output information of the millimeter wave radar in a tunnel scene, reduces the failure possibility of the millimeter wave radar in the tunnel scene, and improves the stability of the millimeter wave radar.

Description

technical field [0001] The embodiments of the present application relate to the technical field of radar detection, and in particular to a tunnel scene detection method and a millimeter-wave radar. Background technique [0002] With the continuous development of the economy and the continuous improvement of people's living standards, more and more people start to use cars as a means of transportation, and cars bring great convenience to people's travel. [0003] Millimeter-wave radar is an important safety auxiliary accessory in automobiles. It obtains the relative position information of the target by emitting electromagnetic waves and receiving the reflected echo of the target, thereby providing a basis for driving safety judgments. [0004] However, for millimeter-wave radar, the tunnel scene is a typical common special scene, its performance will be affected by the complex scattering environment of the tunnel, and a large number of false targets will be output, thereby r...
