Abstract : An object of the patent application is to provide an echo-location system capable of separating otherwise unresolvable adjacent scatterers. Another object is to provide an echo-location system whose response at zero doppler to a point scatterer is the sum of two specified autocorrelation functions. Yet another object is to provide an echo-location system wherein the desired signal components have mutually cancelling autocorrelation sides lobes. Portions of this document are not fully legible.
