[0004] Chinese patent (CN105137423A) discloses a method for real-time detection and separation of multiple moving targets by through-wall radar. This method can quickly realize the separation of moving targets in different areas, but does not take the next step for target information. analysis; Chinese patent (CN103412291A) discloses a realization method based on secondary radar target multipath effect suppression technology, the radar detection area used in this method is limited, and cannot better reflect the judgment of the accuracy of target information

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited thereto.
[0022] The present invention provides an effective target recognition method based on millimeter wave dual radar detection, such as image 3 shown, including the following steps:
[0023] Step 1: Obtain the target information in front of the vehicle through dual radars, including the relative distance D between the vehicle and the target and the angle α of the target relative to the zero coordinate point O of the vehicle; figure 1 , The installation positions of the two radars are symmetrical to the central axis of the car. Compared with the traditional one radar installed on the central axis of the car, the detection range of the two radars is wider.
[0024] Step 2: The radar DSP determines the target area by analyzing the target information, the target area B is the common det...

The invention discloses a valid target recognition method based on millimeter wave dual-radar detection, and belongs to the technical field of traffic safety. The method includes the steps of 1) obtaining front target information through dual radars; 2) determining a target region by analyzing the target information by radar DSPs; 3) performing coordinate conversion of targets in different targetregions respectively; 4) determining, by the radar DSPs, whether the target after coordinate conversion is valid or not; and 5) processing, by the radar DSPs, the valid target information acquired bythe radars to determine whether the target can be considered as an obstacle or not and to further determine whether or not to prompt a driver to take measures. The method in the invention employs dual-radar detection and has a wider detection range as compared with the existing single radar, and the valid target recognition method based on the millimeter wave dual radar detection method enables the radars to detect the front target more accurately.
Description
technical field [0001] The invention belongs to the technical field of driving safety, and specifically discloses an effective target recognition method based on millimeter wave dual radar detection. Background technique [0002] With the frequent occurrence of traffic accidents, the driving safety of automobiles has attracted the attention of major automobile manufacturers. In recent years, with the improvement of science and technology and economic level, the number of automobiles in my country has continued to increase, followed by frequent traffic accidents. According to the statistics of the traffic management bureau of the Ministry of Public Security of my country, more than 65% of the collisions belong to rear-end collisions, and the losses caused are also the largest. It can be seen that the development of a safety anti-collision warning system that avoids longitudinal collisions of vehicles is very important to ensure the driving safety of drivers. significance.
