V beam height indicating system
First Claim
1. IN A GROUND-BASED V-BEAM RADAR SYSTEM HAVING JOINTLY ROTATABLE SLANT PLANE BEAM AND VERTICAL PLANE BEAM ANTENNAS, SAID SYSTEM BEING ADAPTED TO PROVIDE A FIRST SIGNAL PROPORTIONAL TO THE SLANT RANGE FROM SAID ANTENNAS TO A SELECTED ABOVE-GROUND TARGET AND A SECOND SIGNAL PROPORTIONAL TO THE AZIMUTH ANGLE THROUGH WHICH SAID ANTENNAS MUST BE ROTATED FOR THEIR RESPECTIVE PLANES OF TRANSMISSION TO SUCCESSIVELY INTERSECT SAID TARGET, MEANS FOR SUPPLYING AN OUTPUT SIGNAL PROPORTIONAL TO THE HEIGHT OF SAID TARGET CORRECTED FOR EARTH'"'"''"'"'S CURVATURE AND ATMOSPHERIC REFRACTION, SAID CORRECTED HEIGHT LESS A GIVEN FRACTION OF SAID SLANT RANGE SQUARED HAVING A PREDETERMINED LINEAR VARIATION WITH SAID AZIMUTH ANGLE FOR EACH VALUE OF SAID SLANT RANGE, SAID OUTPUT SIGNAL SUPPLY MEANS COMPRISING FUNCTIONAL MULTIPLIER MEANS RESPONSIVE TO SAID FIRST AND SECOND SIGNALS FOR PROVIDING A THIRD SIGNAL PROPORTIONAL TO SAID CORRECTED HEIGHT LESS SAID GIVEN FRACTION OF SLANT RANGE SQUARED, AND MEANS RESPONSIVE TO SAID FIRST SIGNAL FOR INCREASING SAID THIRD SIGNAL BY AN AMOUNT PROPORTIONAL TO SAID GIVEN FRACTION OF SLANT RANGE SQUARED TO PROVIDE SAID OUTPUT SIGNAL PROPORTIONAL TO CORRECTED HEIGHT.
