ABSTRACT:
There is provided a method for non-scanning multi-pixel ranging of a scene, comprising the steps of providing a single detector/receiver associated with a time-delay arrangement, producing a time-arrival distribution of pulse echoes of at least part of a remote scene in a defined ranging plane, receiving said distribution as produced on the ranging plane and conveying it, echo pulse by echo pulse through a plurality of echo pulse conveying means to the single detector/receiver, while introducing a time delay, whereby the echo pulses arrive at the single detector/receiver in a sequential order, and using an electronic logic to reconstruct the time-arrival distribution from the time-delayed echo pulses received by the detector/receiver. Systems for ranging of a scene are also provided.
