Abstract
A method for aberration free optical recording of highly resolved sonar or radar maps wherein a series of one-dimensional holograms is recorded as a function of the receiving time with the help of pulsed sonar or radar and is coherently optically reconstructed, and wherein the one-dimensional holograms are reconstructed through the utilization of a cylindrical lens whose axis of rotation forms an angle with the optical axis such that both the image distance and the image enlargement are independent of distance, the angle being equal to the angle formed between the azimuth coordinate and the optical axis.
