Abstract

Frequency Diverse Arrays (FDAs), are the kind of arrays in which a unique waveform is transmitted from each element by a small carrier frequency offset across the array elements. This small carrier frequency offset in frequency diverse array (FDA) radars leads to the interesting range-angle-time dependent beampattern of FDA radars which is different from the angle only dependent beampattern of phased arrays. In this paper, the received signal from a linear frequency diverse array radar is modeled and simulated and it is shown that this signal is a function of range and angle. Then by investigating the received signal from FDA radars more deeply, the capability of Target localization using one element receiver in these arrays is proved. Finally, based on the intrinsic coupling between the range and angle in FDA radars, an algorithm for Target localization by one element receiver in one-target and multiple-target scenarios is proposed. The simulation results show the validity of the proposed algorithm.
