Claim 17:
18. A method for detection of objects comprising:
transmitting, 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;
receiving, by a receiver, 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;
converting, by the receiver, the one or more received light pulses to output information; wherein the converting comprises applying 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.
