Abstract : A report considered theoretically returns from complex radar targets consisting of several non-resonant scatterers at different ranges. It showed that the power spectrum of such return is given by a constant term plus a series of cosine terms. This report presents the results of experimental work designed to verify the earlier deduction. Experimental measurements consist of photographs of oscilloscope displays for various juxtapositions of two, nearly identical, non-resonant scatterers. The experimental results confirm that the radar returns from a complex target consisting of two scatterers have a constant term and a cosine term. The period of the cosone term is inversely proportional to the separation between the two scatterers. Measured results confirm those predicted by the theory for scatter separations from 0.40 to 3.00 m. (Author)
