Abstract: A method performed by a Lidar detection system includes operating a 2D pixel array of pixel sensors of a detector device to detect an object in a target area of a scanner device, where the scanner device is to scan the target area by emitting a laser light toward the target area; identifying a position of the scanner device when the scanner device is scanning the target area; selecting a portion of the pixel sensors of the 2D pixel array for reading depending on the position of the scanner device to detect the object, where the portion of the pixel sensors are to detect the object by sensing the laser light reflecting from the object; and determining a characteristic of the object based on measurements of the portion of the pixel sensors of the 2D pixel array, where the measurements correspond to the laser light reflecting from the object.

Abstract: A method of determining a temporal position of a received signal within a sample series is disclosed. The method includes sampling a sensor at a sampling frequency to generate the sample series. A matched filter set of matched filters is applied to the sample series to generate a matched filter correlation set of matched filter correlations, wherein impulse responses of respective matched filters correspond to a template signal at the sampling frequency of the sensor shifted by a sub-interval shift. The matched filter correlations are evaluated to determine a received signal sub-interval shift. The temporal position of the received signal within the sample series is determined based on at least the received signal sub-interval shift.

Abstract: A receiver for a light detection and ranging system includes detecting elements, each configured to convert light into an analog detection signal. The receiver includes a first converting element configured to provide a first digital detection signal in response to a first analog detection signal. The first converting element is configured to use a first number of bits to represent the first analog detection signal. The receiver includes a second converting element configured to provide a second digital detection signal. The second converting element is configured to use a second number of bits to represent the second analog detection signal. The second number of bits is greater than the first number of bits. The receiver comprises a processing module configured to determine a first parameter of an object using the first digital detection signal and a second parameter of the object using the second digital detection signal.
