<p>A shipboard radar system for search, said system comprising: a gyro (10); a pitch sensor (11) connected with said gyro to produce an output signal which is a function of the ship's pitch; a roll sensor (12) connected with said gyro to produce an output signal which is a function of the ship's roll; an antenna (17) to radiate a beam of electromagnetic energy; a Rotman lens (24) actuable to move said beam in elevation; and main means responsive to said pitch and roll sensor output signals to control said Rotman lens in a manner to keep said beam pointed toward the horizon.</p> |
