Problems solved by technology

[0003] Most of the existing radar-based anti-collision systems use the radar to detect the RCS value, and the RCS value changes due to the different driving modes of the vehicle, resulting in insufficient characteristics to distinguish object types, and misjudgment often occurs. Users use The experience is not good, and the algorithm is complicated and the real-time performance is not good, which limits the application of the anti-collision system

Embodiment Construction

[0034] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0035] like figure 1 As shown, the embodiment of the present invention provides a target recognition method based on millimeter-wave radar, including:

[0036] Step 10: Obtain reflection points of the target to be measured, and use the reflection points through a predetermined clustering algorithm to obtain target clusters.

[0037] The transmitter module of the radar transmits FMCW. FMCW is the abbreviation of Frequency Modulated Continuous Wave, which means frequency modulated continuous wave, which is a technology used in high-precision radar ranging.

[0038] After the FMCW is reflected by the target to be measured, it is received by the receiving module of the radar to obtain the reflection...

Abstract

The invention provides a target recognition method based on a millimeter wave radar. The method comprises: obtaining a reflection point of the target to be tested, and performing a predetermined clustering algorithm on the reflection point to obtain a target cluster; calculating the area of the largest regular region corresponding to the target cluster; and comparing the area of the largest regular region corresponding to the target cluster with the area of a preset target template to determine the target type. The target recognition method based on the millimeter wave radar improves the accuracy and real-time of target recognition.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a target recognition method based on millimeter wave radar. Background technique [0002] According to statistics, more than 90% of traffic accidents in the world are caused by collisions, so vehicle anti-collision systems have emerged as the times require, and the research on anti-collision systems is an important topic in the field of current automobile driving safety. [0003] Most of the existing radar-based anti-collision systems use the radar to detect the RCS value, and the RCS value changes due to the different driving modes of the vehicle, resulting in insufficient characteristics to distinguish object types, and misjudgment often occurs. Users use The experience is not good, and the algorithm is complicated and the real-time performance is not good, which limits the application of the anti-collision system. [0004] Therefore, the prior art needs to be further improved. ...
