Abstract: This application provides a signal detection method and apparatus, and a radar system, which may be applied to the internet of vehicles, intelligent vehicle, autonomous driving, or intelligent driving field. The signal detection method (700) includes: A first radar transmits a first sounding signal in a first time period of a first frame (710). The first radar transmits a second sounding signal in a second time period of the first frame (720). The first radar receives reflected signals corresponding to the first sounding signal and the second sounding signal (730). The first radar determines a false alarm target based on a difference between a first distance-velocity spectrum and a second distance-velocity spectrum (740). The second sounding signal is a signal obtained through first phase code modulation based on the first sounding signal. The signal detection method can be used to determine the false alarm target, and identify a real target, thereby improving a probability and reliability of detecting the correct target.

Abstract: The present invention discloses an evolved multimedia broadcast/multicast service (eMBMS) processing network element and an evolved multimedia broadcast/multicast service broadcast method. The eMBMS processing network element includes a first transceiver and a first processor. The first transceiver receives an eMBMS bearer application request from an application server. The eMBMS bearer application request includes a broadcast area. The first transceiver sends the broadcast area to a configuration service center, and receives multimedia broadcast/multicast service service area (MBMS SA) configuration information returned by the configuration service center according to the broadcast area. The first processor establishes an eMBMS session resource of the broadcast area according to the MBMS SA configuration information. In the foregoing manner, the present invention can resolve a problem that a broadcast area cannot be dynamically generated under an eMBMS broadcast mechanism.
