Phase shifter control

摘要: A scanning system for a phased array antenna operation at selected frequency between first and second includes the storage (50) of phase shift command signals each shifters (24) coupled to radiating elements antenna. The memory (34) which stores commands is addressed sequentially provide step-wise beam radiant energy addressing (46) accomplished by incrementing count resulting from counting clock pulses (40). Compensation stepped positions difference altering number (54) increment addressing. storing sequences varying temporal spacings are used gating (44) out ones pulses.
