On operation of self-phased arrays under conditions of multipath propagation

This paper gives an analysis of operation of a self-phased array under conditions of multipath propagation (either reflections or jamming signals). A general method for the calculation of directivity of such an array has been proposed. Influence of reflections by way of the pilot signal channel as well as by way of the primary signal channel is taken into account. Some limitations of the approach proposed before have been pointed out and overcome in this paper. It has been shown that an essential reduction in directivity is possible in the case of weak pilot signal or large (close to unity) reflection coefficient
