AN/SPS-46
The AN/SPS-46 is an X-Band seaborne installation designed for water surface craft. It is used for surface search and navigation.
The transmitter is a keyed power oscillator device. The cut paraboloidal reflector with a diameter of 48½ inch (≙ 1,23 m) is fed by a waveguide horn and provides a fan beam pattern with a vertical coverage of 15 degrees.
