A SYSTEM FOR THE EXTENSION OF UNAMBIGUOUS RADAR RANGE WITHOUT DEGRADATION OF VELOCITY INFORMATION

Abstract

The present 455-nautical-mile unambiguous slant range of the Madre radar facility may be extended to 1365 nautical miles without the degradation of available doppler spread and range resolution which results from decreasing the pulse repetition rate. A cyclical stepping of the transmitted frequency spectrum, consisting of two sidebands symmetrically displaced about a common suppressed carrier, is used to preserve coherence of the velocity information conveyed by echoes of the three different frequencies.
