Radar real-time data transmission system, method and device based on residence period

The invention provides a radar real-time data transmission system, method and device based on a residence period. The system comprises a radar main control system, an Ethernet switch, a frequency synthesis system, a signal processing system, a wave beam control system and a data transmission plug-in; the radar main system is connected with the Ethernet switch through a network cable; the frequencysynthesis system, the signal processing system and the beam control system are each connected with the Ethernet switch through a data transmission plug-in connection network cable. The method comprises the following steps: uploading data acquired by a radar to the radar main control system through the Ethernet switch; reading the return information of the subsystems correspondingly connected withthe data transmission plug-in through the data transmission plug-in; transmitting the return information to the radar main control system through the Ethernet switch; after the radar main control system receives the return in
