RADAR TARGET SCATTER SITE (RAT SCAT) VHF MEASUREMENT FEASIBILITY INVESTIGATION
GENERAL DYNAMICS CORP FORT WORTH TX
The material presented in this report is a result of an investigation of the feasibility of making radar cross section measurements in the VHF region at the Radar Target Scatter Site, White Sands Missile Range RAT SCAT. Included are the results of an experimental and analytical investigation which was conducted in the 30- to 80-megahertz region for the purpose of 1 determining the feasibility of making RAT SCAT and 2 defining the range conditions and measurement techniques for use in a feasibility demonstration program to be conducted at RAT SCAT. A study was made of the properties of RAT SCAT soil since a ground plane cross section measurement technique was under consideration. The electrical properties of the soil, in terms of the complex permittivity and associated loss tangent, were measured as a function of moisture, temperature, and sample location. The results of the soil investigation were used in conjunction with a ground plane model programmed on a CDC 1604 to investigate the RF field patterns to be expected at RAT SCAT. These fields were studied as a function of frequency, range, soil conditions, antenna height, and target height.
