<p>#CMT# #/CMT# The device has a rotation circuit provided to carry out the operations of rotation of indicating line connected to radiation diagrams (delta G, delta S), by a combination of signals resulting from receiving channels of an angle error measuring antenna. The rotation of the indicating line follows the oscillation movements e.g. rolling, to which the antenna is subjected. #CMT#USE : #/CMT# Used for stabilizing beams from an angle error measuring antenna subjected to oscillation movements (claimed) e.g. rolling, for a radar embedded on a traveling object e.g. boat, aircraft, and missile. #CMT#ADVANTAGE : #/CMT# The rotation circuit carries out the rotation operations of the indicating line connected to the radiation diagrams, by a combination of signals resulting from receiving channels of the angle error measuring antenna, thus permitting, in the event of breakdown of one of receiving chains, to sequentially transmit the signals to the chain which functions, in order to dispose sequentially two angle error measurement information at the output of the chain. The stabilizing device therefore permits to improve the operational safety of the radar. The arrangement of the device eliminates the need for a particular calibration at the receiving channels. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an angle error measuring antenna beam stabilizing device. delta G, delta S : Radiation diagrams 50 : Receiver 60 : Rolling measuring circuit 61 : Phase-shifter control circuit `(Drawing contains non-English language text)`.</p> |
