  • Radar apparatus for connecting to a gun
    Patent number: 5574461
    Abstract: A radar apparatus provided with a Cassegrain antenna to be mounted on the barrel of a gun. The Cassegrain antenna is of the polarization twist type with a flat adjustable mirror being used to generate a lead angle. In addition, gun-induced vibrations transmitted to the Cassegrain antenna are compensated by adjusting the flat mirror so that the radar beam generated by the Cassegrain antenna is not susceptible to these vibrations.
