Summary:
Adaptive beamforming with Hamiltonian algorithm is proposed for ESPAR antenna. Hamilton′s equations describing the motion of particles are used to solve optimization problems. In an application of Hamiltonian algorithm to ESPAR antenna, the cost function for beamforming is considered as the potential energy. Although the kinetic energy, acted by momentums, does not appear in the issue of the beamforming, the momentums help to provide a more possibility to search the global minimum of the cost function. It is shown that ESPAR antenna with Hamiltonian algorithm can steer its beam and null automatically.
