Abstract

The invention belongs to the field of radar technologies and relates to a radar data transmission device and a radar system. The transmission device comprises a radar transceiver and a data transmitter; the radar transceiver is used for generating frequency sweep signals, wherein the frequency sweep signals have pulse transmission intervals and waiting intervals in the time domain, wherein the waiting intervals are used for isolating adjacent pulse transmission intervals; the data transmitter is connected with the radar transceiver; the radar transceiver is used for providing clock signals tothe data transmitter in the waiting intervals; and the data transmitter performs serial transmission on radar data based on clock signals. With the radar data transmission device and the radar systemof the present invention adopted, the high-speed transmission of multi-channel data can be realized with no additional clock circuits required. The radar data transmission device has the advantages ofsimple structure and low cost.

Description

technical field

[0001] The present invention relates to the technical field of radar, and more specifically, to a radar data transmission device and a radar system. Background technique

[0002] At present, miniaturization and thin terminal have gradually become the design trend of radar system. Thin terminal design means that only a small amount of signal processing or no signal processing is performed on the radar terminal equipment side, but most of the signal processing and data fusion processes are placed in the processing terminal of the radar system (such as the central processing unit, domain processor, etc.), the advantage of this design is that it can improve the performance and efficiency of the radar system. In practical applications, it is necessary to introduce an additional clock signal chip for data transmission between the radar terminal device side and the processing terminal, which will not only increase the cost of the radar system, but also increase the...
