MEASUREMENT OF PROPERTIES OF SPREAD CHANNELS BY THE TWO-FREQUENCY METHOD WITH APPLICATION TO RADAR ASTRONOMY

Abstract

A particular observation scheme based on the twofrequency correlation function approach for the measurement of time-varying spread channels having timestationary Gaussian statistical properties is analyzed. It is shown that the scheme works well for underspread as well as overspread channels. The method also appears to be useful in cases where there is correlation between the signals arriving with different delays. Expressions are derived for the variances of the determined correlation and target-scattering functions derived by double Fourier transformation of the observed correlation function.
