Modified Algorithm for Calculating the Ambiguity Function in the Problem of Estimating the Mutual Time Delays of Wideband Signals

Using the modified algorithm for calculating the ambiguity function, we consider the method of estimation of the mutual time delay of wideband signals, which are recorded by multiposition systems for determining the radiation-source location with the help of the space segment. It is based on the extraction of narrowband channels from the received signals and their further optimal quasi-coherent processing. The criterion of reliability and efficiency of the estimated mutual time delay by the proposed method is studied.
