Abstract: A transmission control method includes steps for obtaining interference information of a first radar on a first frequency band, for example, through listening before transmission. The interference information represents a degree to which the first radar is interfered with on the first frequency band. Transmission duration of the first radar on the first frequency band is determined based on the interference information, where the interference information indicates either a difference between the transmission duration and an initial transmission duration of the first radar, or the transmission duration.

Abstract: A signal transmission method includes a radar detection apparatus selecting a transmit frequency band from a predefined or pre-specified first frequency band. The first frequency band is pre-divided into M sub-frequency bands, and the transmit frequency band includes N sub-frequency bands in the M sub-frequency bands, where a bandwidth of the transmit frequency band is greater than or equal to an operating bandwidth of the radar detection apparatus. A sum of bandwidths of any N−1 sub-frequency bands in the N sub-frequency bands is less than the operating bandwidth of the radar detection apparatus. In addition, a minimum quantity of sub-frequency bands is used to transmit a signal.
