In conjunction with the determination of optical cross-sections of various geometrical bodies, the investigation of the departure from Lambertian optical reflection for several standard surface materials under different angles of incidence is reported. Since the measurements of the near horizontal reflecting power which were made for standard geometrical bodies and models of actual targets did show discrepancies with values calculated according to simple laws of reflection, a more thorough investigation of the actual prevailing relations was indicated.
