The AGC of a conical scan tracking radar IF amplifier is designed using H? 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 to a standard controller, showing significant improvement in system tracking.
