An Adaptative Phased Array Antenna using Simple Algorithm

This paper presents a simple and efficient method allowing the adaptation of electronically steerable antennas using quantized phase shifters. Adaptation aims to maximise the desired signal to external noise ratio. The process which does not involve the knowledge of the directions of external noise sources uses only the quantized phase shifters for adaptation. The performance of this process has been estimated by calculations using a simplified model, by simulation and by experimentation on a sixty element array. The results demonstrate the method efficiency.
