A Dispersed Radar Concept for Air Defense

摘要

This paper suggests a radar configuration for long range (200 km), air defense surveillance. The configuration proposed is multi-static; e.g., several transmitters are used to host one or more receivers. The transmitters are located within a region, or 'farm', of a few hundred meters in extent which is displaced from the receiver by several hundred meters. By spatially distributing the transmit function in this fashion, and displacing it from the receive site, the transmit units can be blinked in a manner similar to that of decoys deployed for monostatic radars. In the approach proposed here, the radiation from the 'decoys' is used as the actual radar transmitter. The report discusses illumination, waveforms, and multiple beamforming trade offs necessary to perform efficient radar operation. It further suggests development efforts which must be conducted before such a system is ready for operational use. (Author)
