Wide-band ambiguity functions (Corresp.)

This note points out that many properties of the conventional ambiguity function have analogs for a true compression-and-delay correlation function; specifically those properties which do not depend upon the former\´s symmetrical treatment of the time and frequency domains. The true compression-and-delay correlation function will be called a "wide-band ambiguity function" to distinguish it from Woodward\´s (1964) ambiguity function.
