Multi-radar networking device and multi-directional target detection method

Abstract

The invention provides a multi-radar networking device and multi-directional target detection method. The device comprises multiple radars and an upper computer; the radars are interactively connectedwith the upper computer; each radar is provided with a GPS module, an electronic compass module and an automatic learning module, the radar is used for detecting a target and reporting the target information of the radar to the upper computer, and the GPS module is used for positioning the longitude and latitude information of the radar and reporting the longitude and latitude information of theradar to the upper computer via the radar; the electronic compass module is used for detecting the azimuth information of the radar and reporting the azimuth information of the radar to the upper computer via the radar; and the automatic learning module is used for automatically learning a surrounding environment and setting different thresholds for different distance units of the radar. Detectionin multiple directions is achieved, the problem that the azimuth range is limited when the radar is used for detecting the target is solved, and the dead angle of the radar is avoided.

Description

technical field [0001] The invention belongs to the technical field of linear frequency modulation continuous wave radar target detection, and in particular relates to a multi-radar networking device, and also relates to a multi-directional target detection method combining multiple radars. Background technique [0002] Chirp continuous wave radar has high range resolution, simple structure, small size, light weight and good low intercept probability characteristics, and has been widely used in the field of intelligent monitoring. The target detection technology of chirp continuous wave radar is of vital significance in the intelligent monitoring system of unattended occasions or uninhabited restricted areas, and directly determines the safety performance of the monitoring system. [0003] In the intelligent monitoring system, there are also high requirements for the anti-false alarm of the radar. However, the detection radars currently used in monitoring systems generally ...

AI Technical Summary

Problems solved by technology

However, the detection radar currently used in the monitoring system generally adopts a fixed target detection threshold, which is difficult to guarantee the anti-false alarm capability of the radar, and also limits the low interception performance of the radar to a certain extent.

[0004] Since the direction of the general radar is fixed, and the range of the antenna detection target azimuth is limited, it is easy to have monitoring blind spots
