The goal of sparse FIR filter design is to minimize the number of nonzero filter coefficients, while keeping its frequency response within specified boundaries. Such a design can be formally expressed via minimization of l0-norm of filter’s impulse

In antenna array design, low dynamic range ratio (DRR) of excitation coefficients is important because it simplifies array’s feeding network and enables better control of mutual coupling. Optimization-based synthesis of pencil beams allows explicit

In this work, design of unequally spaced antenna arrays with uniform excitation is considered. The design is based on numerical optimization of array's sidelobe power. The corresponding optimization problem is nonconvex and highly nonlinear. Therefor

Optimization-based methods for pencil-beam design often incorporate controlling the dynamic range ratio (DRR) of excitation coefficients. However, constraining the DRR causes the deterioration of sidelobe region, in which some lobes may rise and even

Array pattern with reduced dynamic range ratio (DRR) of excitation coefficients simplifies the design of array's feeding network. However, constraining DRR pushes small coefficients towards higher values, which might not be optimal from the array-pat

The design of sparse FIR filters leads to combinatorial optimization problems, which can be rarely solved in an acceptable time. Therefore, many approximate methods have been considered. Most of them are focused on the design of linear-phase filters

Classical imaging system projects the surface of a 3-D object onto a 2-D sensor. The surface occupies only a small part of the observed volume. Therefore, the samples representing the volume form a sparse signal. We exploit this property in reconstru
