ABSTRACT:
An antenna system determines the true time delay in two or more correlated signals without a priori knowledge of the time relationship between the signals and uses the determined true time relationship to achieve maximum signal combinations of received and/or transmitted signals, increased receive G/T and/or transmit EIRP. The antenna system can provide adaptive beam steering with optimal time delays for each antenna element of a phased array and can combine distinct antenna apertures to create a larger effective antenna aperture.
