Dynamic lead guidance system for homing navigation
Abstract
Abstract A SYSTEM AND METHOD OF GUIDING HOMING MISSILES TOWARD LOW MANEUVERABILITY TARGETS. DYNAMIC LEAD NAVIGATION IS IMPLEMENTED WITH A BODY FIXED DETECTOR AND A TWODEGREE-OF-FREEDOM POSITION GYROSCOPE. THE POSITION GYRO CAN BE A PART OF THE NORMAL MISSILE AUTOPILOT AND NEED NOT REPRESENT AN ADDITIONAL INSTRUMENT. IN FLIGHT TOWARD A TARGET, A TARGET SEEKER, WHICH YIELDS A PROPORTIONAL OUTPUT, MEASURES THE ANGLE BETWEEN THE MISSILE-TARGET LINE-OFSIGHT AND THE MISSILE CENTER LINE. AN INSTRUMENT GYRO ALLOWS AN ATTITUDE ANGLE TO BE MEASURED. THE DIFFERENCE BETWEEN THESE TWO ANGLES IS OBTAINED, PROVIDING THE MISSILE-TARGET LOOK-ANGLE OR ERROR SIGNAL FOR DIRECTING THE MISSILE TOWARD THE TARGET.
