Abstract

The invention discloses a radar test method, device and equipment and a storage medium. The method comprises steps of obtaining the first power of a radar signal transmitted by a to-be-tested radar and the second power of a detection signal, the detection signal being obtained after the radar signal is detected by a target antenna, and the target antenna being fixed at a target position; carrying out loss analysis based on the first power and the second power to obtain path loss information; the radar to be measured being controlled to position and identify the target object under an interference signal, target positioning information corresponding to the interference signal being obtained, and the interference signal being a signal of target power emitted by an interference source through a target antenna; performing power calibration on an interference signal received by the radar to be measured based on the target power and the path loss information to obtain calibration power of the interference signal; and based on the target positioning information, generating an anti-interference test result of the to-be-tested radar under the interference signal of the calibration power. The method is advantaged in that objectivity and accuracy of an immunity test result can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicle radar, in particular to a radar testing method, device, equipment and storage medium. Background technique [0002] With the increasing application of automotive millimeter-wave radar in the field of autonomous driving, its performance in terms of noise immunity has received extensive attention. The existing radar immunity test method is to generate various interference signals through interference sources, interfere with the radar to be tested in the working state and count the target recognition situation of the radar to be tested under different power interference signals, and compare the interference source The displayed transmission power value is used as the interference power value received by the radar to be tested. [0003] However, even if the interference source transmits interference signals of the same frequency, when the angle or distance between the interference source an...
