<p>Radar apparatus provided with a Cassegrain antenna (1, 7-9) to be mounted on the barrel of a gun. The Cassegrain antenna is of the polarization twist type, a flat, adjustable mirror (9) being used for generating a lead angle. In addition, gun-induced vibrations transmitted to the Cassegrain antenna (1, 7-9) are compensated by adjusting the flat mirror (9) such that a radar beam generated by the Cassegrain antenna (1, 7-9) is not susceptible to these vibrations.</p> |
