Beampattern Design Using Riemannian Manifold for Frequency Diverse Array Considering Jammers

This paper investigates a two-dimensional range-angle beampattern synthesis method for jammer suppression using a frequency diverse array (FDA) multiple-input multiple-output (MIMO) framework, where the transmit waveform, receive filter, and frequency increment are optimized. At the problem formulation stage, the objective function is chosen as the minimization of the squared error between the devised and desired beampattern, where the beampattern response corresponding to the target region atta
