To solve the shortage of the application of conventional methods in beam broadening of phased array antennas, this paper has presented a method for beam broadening by constructing an initial phase based on particle swarm optimization (PSO) algorithm and genetic algorithms (GAs). The paper takes an S-band phased array antenna as an example to construct the same initial phase of linear distribution,...
This paper studies pattern optimization of an offset parabolic reflector antenna with phased array feeds. Considering quantization requirements, to solve optimum weight vector of phased array feeds can be modeled as integer programming problem, which is optimized with the quantum particle swarm optimization (QPSO) algorithm. The optimization with QPSO to determine the quantized element weights is...
Investigations on conformal phased array pattern synthesis using a novel hybrid evolutionary algorithm are presented. First, in order to overcome the drawbacks of the standard genetic algorithm (GA) and the particle swarm optimization (PSO), an improved genetic algorithm (IGA) and an improved particle swarm optimization (IPSO) algorithm are proposed by introducing novel mechanisms. Then, inspired...
