The material presented comprises the results obtained from the successful demonstration of the feasibility of making radar cross section measurements in the VHF band at the Radar Target Scatter Site RAT SCAT, White Sands Missile Range. A test program was defined by which the electronic system, antenna system, range designs, and target supports were evaluated. The coherent electronic system design was such that both CW and pulsed operation was possible. The design included an RF cancellation network for CW short range operation and an IF cancellation network for pulsed operation at longer ranges. Both a single antenna-hybrid system design for use with a short range design and a dual-antenna system design for use at the longer range were implemented and tested. A range length of 350 feet was used to evaluate the short range CW cancellation technique and a range of 1500 feet was used to evaluate the pulsed technique. Test frequencies of 30, 45.5, 61.1, and 92.2 megahertz were used to obtain information relative to 1 transmitter and receiver performance, 2 single antenna hybrid isolation, 3 dual antenna isolation, 4 RF field gradients, 5 background levels, 6 cross section measurement capability, and 7 feasibility and requirements for adopting the electronic system and range designs into an operational system at RAT SCAT.
