Abstract

In this paper, we present a different approach to the problem of estimating the angle of arrivals (AOAâ??s) of D targets in Frequency-Hopped signaling sensors array for active systems, with D smaller than the number of sensors element, L. This method is based on the application of a new proposed model of received data available in different channels. The simulations results show that this approach improves the resolution in the estimation of the angle of arrivals compared with Monotone-Frequency signaling case.
