Method for estimating coherent properties of radar signals

We propose a method for estimating coherent properties of signals within the framework of the correlation theory. A quantitative measure of coherence is obtained in the form of entropy of the signal energy distribution over the eigensubspaces of the correlation matrix of the signal. Examples are given to illustrate the effectiveness of the obtained measure. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 49, No. 1, pp. 82–87, January 2006.
