Abstract
A frequency and phase scannring antenna array svstem having the capability of finding simultaneously the frequency and the direction of arrival of the incident wave by using simple amplitude measurements is described. Microstrip wide slot is used as the antenna array element due to its broad bandwidth. The incident RF wave received by the antenna array is fed to a detector logarithmic video amplifier(DLVA) to determine its amplitude. Finally, the maximum likelihood estimation procedure is applied to the observation vector formed by the DLVA outputs to estimate the frequency and the angle of incidence of the incoming wave.
