Abstract: This application provides example detection signal transmitting methods, detection apparatuses, and storage medium. One example method includes determining an orientation of a field of view of a detection apparatus. One of a plurality of anti-interference parameters can then be selected as a target anti-interference parameter based on the orientation of the field of view of the detection apparatus and according to a predefined rule, where the plurality of anti-interference parameters are determined according to the predefined rule. A detection signal can then be transmitted based on the target anti-interference parameter.

Abstract: This application provides a radar information transmission method, an apparatus, and a system, to reduce interference between radars, and relates to the field of wireless communication technologies. In the method, a first device receives a first radar signal that carries information from at least one device. The first device obtains first parsing data based on the first radar signal. The first device determines information from a second device based on a location of one or more information points indicated by the first parsing data in the first parsing data. According to this solution, the first device and the second device can use a radar signal to carry information, to implement information transmission between radars, thereby avoiding mutual interference.
