Polarised beampattern synthesis against array manifold mismatch

Beampattern Synthesis with Linear Matrix Inequalities Using Minimum Array Sensors

A new beampattern synthesis formulation is proposed to compute the minimum number of array sensors required. In order to satisfy all the prescribed specifications of the beampattern, the proposed method imposes linear matrix inequality (LMI) constraints on the beampattern as developed by Davidson et al., which remove the need to discretize the beampattern region. As the proposed formulation is ...

Adaptive Beampattern Control Using Quadratic Constraints for Circular Array Stap

A general framework for adaptive and non-adaptive spacetime beampattern synthesis using quadratic beampattern constraints with minimum mean-square error (MMSE) and linearly constrained minimum variance (LCMV) beamforming is presented. Main beam and sidelobe pattern control is achieved by imposing a set of inequality constraints on the weighted mean-square error between the adaptive pattern and ...

Manifold studies of nonlinear antenna array geometries

In this paper, the manifold of a general twoor threedimensional (2-D or 3-D) array of sensors is studied using differential geometry. By considering the azimuth and elevation angles as the parameters of interest, a manifold surface is formed embedded in a multidimensional complex space. Initially, this surface is investigated by establishing a number of differential geometry parameters associat...
