Correlation processing of narrow-spectrum signals with unknown parameters in a passive multiposition instrument for measuring the coordinates of continuous radiation sources

A method of increasing the accuracy characteristics of passive multiposition measuring instruments when receiving narrow-spectrum signals, based on converting the initial signal spectrum in order to narrow the main lobe of the autocorrelation or cross-correlation functions of the received signal, is proposed.Translated from Izmeritelnaya Tekhnika, No. 10, pp. 49–52, October, 2004.
