Radar signal detection device and method

Abstract

The invention provides a radar signal detection device and method, and the device comprises a signal receiving and transmitting assembly, a laser ranging module, and a controller which is electrically connected with the signal receiving and transmitting assembly and the laser ranging module. Performing frequency sweeping on the radar signal emitted by the radar to be measured according to a frequency sweeping mode corresponding to the frequency band of the radar signal emitted by the radar to be measured, and transmitting the radar signal subjected to frequency sweeping to the controller; the laser ranging module is used for transmitting a laser beam to a radar to be measured and receiving a reflected laser beam of the radar to be measured, determining a distance value between the device and the radar to be measured according to the laser beam and the reflected laser beam, and sending the distance value to the controller; the controller is used for determining the radiation power and the frequency band of the to-be-detected radar according to the radar signal and the distance value. The detection cost of the to-be-detected radar is reduced, and the radiation power and the frequency band can be rapidly obtained.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a radar signal detection device and method. Background technique [0002] At present, the millimeter-wave radar in the 76-81GHz frequency band may be installed on the whole vehicle or on the beam or gantry of the road according to different application scenarios. As the installed capacity of vehicle-mounted millimeter-wave radars and traffic millimeter-wave radars increases year by year, there are many brands, models, and frequency bands of millimeter-wave radars, making it difficult to detect. During the use of millimeter-wave radar, it is necessary to regularly check whether it is working normally. The main concern of millimeter-wave radar indicators is whether the radiation power and working frequency band meet the requirements of the instructions and laws and regulations. At present, there are three ways to detect the radiation signal of millimeter-wave radar in the 76-81GHz f...
