Abstract

The frequency diverse array (FDA) radar has range-dependent and time-varying characteristics, which can eliminate the limitation of the phased array whose beampattern is angle-dependent only. FDA can create more possibilities due to its unique features. However, the range-angle coupling characteristic of the conventional FDA makes it difficult to be an effective way in anti-jamming and detection areas. In this paper, adopting adaptive genetic algorithm based thinned array, a beamforming method of FDA with non-linear frequency offset is proposed, which can form a sharp dot-shaped beampattern. Simulations demonstrate the validity of the method.
