Abstract:

A coherent optical processor for displaying a signals ambiguity function is described. The required time delay is realized by 45 deg. rotations of two identical input transparencies, and the Doppler shift by a 1-D Fourier transformation. The modulus squared of the entire ambiguity function is displayed in the output plane Doppler shift-time delay. Examples of the optically computed ambiguity functions for single and double pulse signals are sshown to be in excellent agreement with the theory. Advantages of this approach over various alternative schemes are discussed. Author
