Abstract
A chirped illumination LIDAR system having a transmitter that may include a pulsed radiation illuminator that is followed by a beam forming optics. The transmitter may be configured to output, during each illumination period of a sub-group of illumination periods, a first plurality of radiation pulses that form a decimated chirp sequence of radiation pulses; the decimated chirp sequence is a sparse representation of a chirp signal. A receiver of the system may be configured to receive, during each reception period of a sub-group of reception periods, one or more received light pulses from one or more objects that were illuminated by the one or more radiation pulses transmitted during each illumination period. The receiver may include multiple radiations sensing elements, multiple shutter circuits, and multiple processing circuits for converting the one or more received light pulses to output information; wherein the multiple shutter circuits may be configured to apply a shutter function on intermediate signals, the intermediate signals represent radiation sensed by the multiple radiations sensing elements, wherein the shutter function represents the chirp signal.
