Abstract
This application provides a signal detection method and apparatus. One example method includes: transmitting, by a first radar, a first sounding signal in a first time period of a first frame; transmitting, by the first radar, a second sounding signal in a second time period of the first frame; receiving, by the first radar, reflected signals corresponding to the first sounding signal and the second sounding signal; and determining, by the first radar, a false alarm target based on a difference between a first distance-velocity spectrum and a second distance-velocity spectrum, wherein the second sounding signal is a signal obtained through first phase code modulation based on the first sounding signal, the first distance-velocity spectrum is obtained based on a first reflected signal corresponding to the first sounding signal, and the second distance-velocity spectrum is obtained based on a second reflected signal corresponding to the second sounding signal.
