PROCESS FOR THE AUTOMATIC TRACKING OF THE DIRECTIONAL BEAM OF A PHASED ARRAY ANTENNA

摘要

A device for automatic tracking of the directional beam of a phased array antenna which includes a plurality of modules arranged in rows and columns. A part of the output voltages of the modules are coupled together to develop signals which are indicative of either the even numbered or odd numbered rows and columns of modules. The output signals are coupled to phase discriminators which develop positive or negative voltages in dependence on the sign of the angle of incidence of the arriving signal. The control voltage is then used in a closed regulating circuit to control delay lines associated with each of the modules.
