  • Radar signal processing in advanced driver assistance systems
    Patent number: 12468030
    Abstract: An advanced driver assistance system (ADAS) radar includes at least one transmit antenna coupled with a vehicle, the at least one transmit antenna configured to transmit radar signals from the vehicle towards a scene of interest, at least one receive antenna coupled with the vehicle, the at least one receive antenna configured to receive reflected radar signals, and at least one processor. The processor is configured to execute computer-executable instructions to obtain multiple time-samples of the reflected radar signals from the at least one receive antenna at specified periodic intervals, execute an auto-correlation algorithm on the obtained multiple time-samples, normalize a ratio of zeroth lag and first lag according to an output of the auto-correlation algorithm, and compare the normalized ratio of the zeroth lag and the first lag to a specified threshold, to determine whether the reflected radar signals include an identified road clutter object.
