Abstract
A method includes generating emitted signals using transmitter elements and measuring received signals using receiver elements. The received signals are reflected portions of the emitted signals and the received signals correspond to one or more targets. The method also includes applying a first matched filter to the received signals to determine range information for the received signals, filtering the received signals based on the range information to define filtered signals, and determining calibration parameters using the filtered signals. The method also includes correcting the received signals using the calibration parameters to define calibrated signals and determining angle of arrival information for the received signals using the calibrated signals.
