The automatic gain control (AGC) of a conical scan tracking radar IF amplifier is designed using H/sub /spl infin// synthesis. It is shown that this technique is particularly suited for this problem because of its loop shaping capabilities and because it can tackle particular frequencies effectively, providing a correct balance among closed-loop stability, fast response to echo changes, and rejection of frequencies other than the echo modulation. Two controllers are implemented and compared with a standard controller, showing significant improvement in system tracking.
