Abstract

The embodiment of the invention provides a cooperative detection method and device for multi-radar space registration based on signal fusion. The method comprises the following steps: determining relative position information of a detection target and each cooperative detection radar; detecting the relative position information of the target and each cooperative detection radar, and adjusting thebeam width of each cooperative detection radar, so as to enable the ground detection regions of the beams of each cooperative detection radar to be consistent; for each cooperative detection radar, determining a weighting coefficient of an antenna array element of the cooperative detection radar by adopting a beamforming algorithm with controllable beamwidth according to the determined beamwidth;and transmitting a detection beam to a detection target based on the determined weighting coefficient of the antenna array element, and sending a reflected signal to a signal fusion processing centerthrough an underground optical fiber, so that the signal fusion processing center integrates the signals sent by the cooperative detection radars and performs cooperative processing. The complexity ofspace registration can be reduced, and multi-radar cooperative detection based on signal level data fusion can be realized.

Description

technical field [0001] The present invention relates to the technical field of sensing base stations, in particular to a method and device for cooperative detection based on signal fusion and multi-radar spatial registration. Background technique [0002] The data fusion of the existing multi-radar networking system is roughly divided into three levels: track fusion, decision fusion, and signal fusion. The first two belong to the fusion of information level. Before data fusion, each radar needs to process the echo signal to a certain extent, and then transmit the processed information to the fusion center. This will result in the loss of some information. Compared with information-level fusion, signal fusion can transmit more original echo information, and unified processing in the fusion center can greatly improve the radar detection performance. [0003] However, the sampling period and beam shape of each radar are different. If the detection data of each radar is direct...
