Abstract
A method for operating a frequency modulated continuous wave (FMCW) radar system is provided that includes generating digital intermediate frequency (IF) signals from radio frequency signals received by a small receive antenna array in the FMCW radar system and processing the digital IF signals to determine whether or not a gesture was performed.
Claims20
A method for operating a frequency modulated continuous wave (FMCW) radar system, the method comprising:
- generating digital intermediate frequency (IF) signals from radio frequency signals received by a small receive antenna array in the FMCW radar system;
- and
- processing the digital IF signals to determine whether or not a gesture was performed.
A frequency modulated continuous wave (FMCW) radar system comprising:
- a small receive antenna array;
- a receive channel for each receive antenna in the receive antenna array, each receive channel coupled to a respective receive antenna to generate a digital intermediate frequency (IF) signal from a radio frequency signal received by the receive antenna;
- and
- a processor coupled to each receive channel to process the digital IF signals to determine whether or not a gesture was performed.
