Abstract
A system for correcting the distortion of the plane waves passing through the radome covering an antenna on a missile airframe by nutating the airframe, in both pitch and yaw to quantify the error in accordance with the nutation, and then determining the radome boresight error, and then correcting it in accordance with the solution of certain algorithms.
Claims4
In a vehicle guidance system having a radar controlled steering means for guiding a vehicle to a target, said steering control means having azimuth and elevation control output signals for controlling the steering of said vehicle, the antenna for said radar being enclosed in a radome, a boresight error rate correction system for said radome, said boresight error rate correction system comprising:
- means for nutating said vehicle;
- said antenna receiving return signals from said target through said radome;
- means for processing return azimuth and elevation signals received from said target to determine the true line of sight between said target and said antenna.
