Abstract:
1. A radar system comprising: a transmitter adapted to transmit radar signals into a region of a cluttered environment to illuminate said region with a signal modulated as a regular sequence of pulses at a given pulse rate; a receiver adapted to receive return signals, of said radar signals, reflected from within said region, and representing observations; and a processor adapted to process the return signals to extract data, including clutter related data, for said region, wherein said processor is operable to integrate said return signals coherently and subject to a limit on the range and range rate associated with the observations that the return signals represent, within which limit said radar operates substantially unambiguously in range and range rate at said pulse rate, and wherein said limit on the range and range rate is expressed by the inequality: where R is the range and dR/dt is the range rate associated with the observation, c is the speed of light, and F op is operating frequency of the radar system.
