Zusammenfassung:A system for controlling an active electronically scanned array (AESA) antenna, which enables the AESA antenna to switch rapidly between different antenna states, includes memories (38) connected to a common address bus (40). Each memory (38) is also connected to a digitally controlled RF signal transmission block (32) within the AESA antenna, and stores digital control words for the digitally controlled RF signal transmission block (32). When a new address is provided on the address bus (40), each memory (38) outputs a new digital control word to its respective digitally controlled RF signal transmission block (32), causing a change in the state of the AESA antenna.
