A radar detection method with receive antenna calibration includes: forming a detection matrix from signals detected by an arrangement of receive antennas in response to chirps transmitted by an arrangement of transmit antennas, the detection matrix having multiple rows corresponding to the chirps, multiple columns corresponding to a sample of the signals, and multiple planes corresponding the receive antennas; deriving a range matrix by performing a frequency transform on a portion of each row of the detection matrix; deriving a velocity matrix by performing a frequency transform on a portion of each column of the range matrix; deriving a direction-of-arrival matrix by performing a frequency transform on a portion of one or more layers of the velocity matrix; analyzing the direction-of-arrival matrix to determine a current peak width; and adjusting, based on the current peak width, phase shifts associated with one or more antennas.

Various embodiments of the present technology comprise a method and apparatus for high dynamic range imaging. According to various embodiments, the method and apparatus for high dynamic range imaging is configured to select the 'best' signal for each pixel location to construct an HDR output. In one embodiment, the 'best' signal is select among various pixel signals and the pixel signal selected as the 'best' signal is based on the value of the pixel signals and identification of non-saturated. If only one pixel value for a particular pixel location is non-saturated, then the &#x201c;best&#x201d; signal is the non-saturated signal. If more than one pixel value is non-saturated, then the &#x201c;best&#x201d; signal is the pixel signal with the greatest value. If two more pixel values are non-saturated and both have equally great values, then the &#x201c;best&#x201d; signal is the pixel signal with the shortest integration time.
