Target support parameters associated with radar reflectivity measurements

Theoretical and measured data are presented pertaining to background levels which can be achieved with the conventional target supports: cellular plastic columns and suspension lines. In each case, target weight, measurement frequency, and target cross section are related and presented in the form of support capability curves. Circular Styrofoam [1] columns are used as typical of cellular plastic supports; the theory for computing cross section of other materials and shapes is also presented. Nylon lines were used as typical suspension supports. A brief discussion of other support techniques is included, but the discussion is limited primarily to the spin drop and dielectric tube supports.
