Problems solved by technology

The biggest problem is that it can only be applied to the situation where there is a single target in the radar detection range. When there are multiple targets in the radar detection range, it cannot be detected

Abstract

The invention provides a target recognition method based on millimeter-wave radar data, comprising the following steps: S100, performing single-frame radar data scatter information extraction and de-noising processing; S200, performing multi-frame radar data overlay processing; S300, performing radar target segmentation and determining positions; and S400, based on target recognition of a classifier, forming a characteristic sample space for millimeter-wave radar target recognition by one-dimensional range profile of each segmented target along radial direction, randomly dividing the characteristic sample space into a training sample subspace and a detection sample subspace, and performing sample training and detection by adopting the classifier, thus radar data of each target is extractedby segmenting the target; and performing the target recognition on basis of the data, so that correct radar target recognition rate is effectively improved, multi-target recognition is also realized,and important reference data can be provided for a radar target recognition method.

Description

technical field [0001] The invention relates to the technical field of target recognition, in particular to a target recognition method based on millimeter wave radar data. Background technique [0002] The signal of the millimeter-wave radar can penetrate rain, fog, and dust, and is not affected by light conditions, supporting all-weather work. At the same time, millimeter wave radar has a high degree of integration and sensitivity. Therefore, millimeter-wave radar, which has absolute advantages in reliability, accuracy, and distance perception, has gradually become the main force of the entire sensor system, and is used in target recognition in many industries such as automotive electronics, drones, and intelligent transportation. [0003] The process of radar target recognition technology is generally to extract the relevant information and stable features of the target from the echo of the radar target, construct the feature template library of the known target, then us...
