Figure 4From: Instantaneous altitude estimation of maneuvering target in over-the-horizon radar exploiting multipath Doppler signatures Illustration of the IF estimation process. (a) Original Doppler signature, (b) after coarse stationarization, (c) Stationarization with accurate Doppler estimate, (d) after removal of the stationarized component, (e) stationarized with one of the remaining components, and (f) after removal of the stationarized component.Back to article page
