Estimation of the direction of arrival of broadband signals using a single snapshot

Estimation of the Direction Of Arrival (DOA) of broadband signals is presented based on a single snapshot of data using an interpolation methodology. The goal is to simultaneously estimate the DOA of all the signals along with their respective frequencies of operation using a single snap shot of the voltages measured at the antennas. Numerical results are presented to illustrate the applicability of this novel methodology.
