A new population-based metaheuristic optimization algorithm named Simulated Kalman Filter (SKF) is proposed as an adaptive beamforming algorithm for adaptive array antenna. SKF optimization algorithm is inspired by the estimation capabilities of Kalman Filter. Each agent in the population of SKF acts as one Kalman Filter where it finds the solution using standard Kalman Filter framework. SKF consists of simulated measurement process and a best-so-far solution as a reference. SKF estimates the weights of individual elements in an array which maximizes the signal to interference plus noise ratio (SINR). SKF is also compared with Adaptive Mutated Boolean Particle Swarm Optimization (AMBPSO) from existing work and is proven to be better.
