ABSTRACT:
A beam switching processor operable to detect a microwave amplitude distrtion associated with an array of receiving antenna ports and to close a single-pole, multiple-throw microwave switch to that port in a matched array of transmit antenna ports which corresponds to the receiving antenna port having the maximum signal amplitude. The receive antenna signals are log amplified and subsequently processed in a logic section which indentifies the input port having the highest energy level and energizes the corresponding microstrip switch-driver circuit.
