Radar data buffering

A method for operating a radar sensing system comprising a transmitter and a receiver, the receiver having an analog-to-digital converter (ADC) and a buffer, the method comprising:

• transmitting, with the transmitter, radio signals;
• receiving, with the receiver, radio signals that include the transmitted radio signals transmitted by the transmitter and reflected from objects in an environment;
• sampling, with the analog-to-digital converter of the receiver, the received radio signals and outputting data samples;
• storing the data samples in the buffer of the receiver;
• selecting, with a controller, two or more modes of operation for the buffer;
• operating the buffer in the selected two or more modes of operation with a same set of data samples stored in the buffer and outputting data samples from the buffer;
• receiving, with a post-buffer processor, the data samples output from the buffer;
• and performing, with the post-buffer processor, at least one of correlation processing to determing ranges of the objects and Doppler processing to determine a velocity of the objects.
