Over-the-horizon backscatter radar
Abstract
This paper describes a recently constructed over-the-horizon backscatter (OTH-B) radar system covering as many as 4,800,000 sq nautical miles over a distance of 1800 nautical miles. This HF system operates at frequencies from 5 to 28 MHz. The radar's 3630-ft-long transmitting antenna is divided into six subarrays to accommodate different operating frequencies. Three sets of these arrays are located at the east coast radar system transmit site near Moscow, Maine. The transmitter is powered by 12 10-kW tubes per sector, emitting 360 kW of radiated RF power. The signal processing software correlates the receiver radar track data with flight patterns of unknown aircraft and flight plans of friendly aircraft; twenty-nine computers perform the signal analysis and processing function of the receiver.
