Claim 0:
1. A chirped illumination LIDAR system comprising:
a transmitter; and
a receiver;
wherein the transmitter comprises a pulsed radiation illuminator that is followed by a beam forming optics;
wherein the transmitter is 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;
wherein the receiver is 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;
wherein the receiver comprises 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 are 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.
