Abstract
A radar system includes a first radar sensor comprising a data combination system and a plurality of radar monolithic chips, wherein each radar monolithic chip includes a first radio frequency front end and a first microprocessor. The first microprocessor is configured to preprocess echo data obtained by the first radio frequency front end. The data combination system is configured to combine and transmit the preprocessed echo data, wherein a processor performs post-processing on the preprocessed echo data to generate point cloud data of the radar system.
Claims20
A radar system, comprising:
- a radar sensor comprising:
- a plurality of radar monolithic chips, wherein each of the radar monolithic chips comprises:
- a radio frequency unit configured to receive echo data;
- and
- a microprocessor coupled to the radio frequency unit and configured to preprocess the echo data by performing downsampling on X digital chirp signals received from the radio frequency unit to obtain first data comprising Y digital chirp signals, wherein both X and Y are positive integers greater than one, and wherein Y is less than X;
- and
- a data combination module, comprising:
- a processor configured to combine the first data of each of the radar monolithic chips to obtain combined data of the radar sensor;
- and
- a communication interface coupled to the processor and configured to transmit the combined data;
- and
- a central processing unit configured to perform post-processing on the combined data to obtain second data,
- wherein the second data are configured to generate point cloud information of the radar system.
