Target identification method and device, electronic equipment and storage medium

Abstract

The invention relates to the technical field of radar signal processing, in particular to a target identification method and device, electronic equipment and a storage medium. Reflection point data of the detection object is extracted through the sliding window, at least one candidate effective target point set is determined according to the reflection point data in the sliding window, and a target corresponding to the candidate effective target point set is a candidate effective target. The sliding window is a time window for sampling reflection point data, and one time window corresponds to one time period; therefore, according to the embodiment of the invention, the reflection point data appearing in a period of time can be acquired, and the candidate effective target point set is determined according to the reflection point data appearing in the period of time. Compared with a mode of determining the effective target through the reflection point data appearing at a certain moment, the candidate effective target identified through the mode of determining the candidate effective target through the reflection point data within a period of time is higher in accuracy.

Description

technical field [0001] The present invention relates to the technical field of radar signal processing, in particular to a target identification method, device, electronic equipment and storage medium. Background technique [0002] Millimeter waves are electromagnetic waves between infrared light waves and microwave frequency bands. The wavelength of the millimeter wave is between 1mm and 10mm, and the corresponding frequency range is 30-300GHz. Millimeter wave radar is an electronic device that uses millimeter waves to detect targets. When the millimeter-wave radar is working, the radar antenna radiates the millimeter-wave in the atmosphere, and the millimeter-wave propagates in the atmosphere at a speed close to the speed of light. If the target happens to be within the millimeter-wave beam radiated by the radar antenna, the target will intercept a part of the millimeter-wave and send it to the ground. Scatter the intercepted millimeter wave in all directions to form a r...

Problems solved by technology

[0003] In related technologies, since the millimeter wave radiated by the radar antenna may be reflected by objects other than the target, the reflected signal of the millimeter wave is divided into multiple paths for transmission; At the end, they will superimpose each other according to their respective phases and cause interference, that is, multipath interference

Multipath interference causes the millimeter-wave radar to detect the target, and the reflected signal received by the target changes in amplitude and phase, resulting in detection errors
