The study was conducted to explore the hypothesis that errors in radar installation and operation that are caused by certain mechanical deformations could be analyzed and corrected. The technique used was to place small optical mirrors at precise positions on a radar reflector. The sun images thus reflected on photographic paper make it possible to 1 measure the actual surface deformation of a large radar reflector to an accuracy that the degree of conformance with specifications can be evaluated and 2 to provide the data required to adjust the feedhorn focal point to an acceptably accurate position. The input of these measurements into radar calibration data before and after a tracking operation would greatly improve the accuracy of the radar system. Author
