Secure hyperbolic guidance using noise signals and correlation detection










Image Number 6 for United States Patent #3936827.

A method for use in controlling the flight of an aircraft which includes radiating from two base stations respectively a first noise signal and a second noise signal identical to said first noise signal but at a slightly different frequency and at a controlled interval with respect thereto, receiving both of said signals at said aircraft, simultaneously deriving at said aircraft a first oscillating voltage related to the envelope of the correlation function of said signals at a first delay time therebetween and a second oscillating voltage related to said envelope of said correlation function of said signals at a second delay time therebetween, subtracting said voltages to yield a difference voltage, and utilizing said difference voltage to control the airfoils of said aircraft.
