Abstract
A NEW CONTROL TECHNOLOGY IS AVAILABLE WHICH CAN BE USED TO DESIGN AN ADAPTIVE, REAL-TIME COMPENSATOR TO COUNTER THE EFFECTS OF RADOME BORESIGHT ERRORS IN RF HOMING MISSILES. THIS CONTROL THEORY MAKES USE OF THE FACT THAT RADOME ERRORS ARE NOT COMPLETELY RADOM, BUT MAY BE DESCRIBED BY THE WEIGHTED SUM OF A FINITE NUMBER OF FUNCTIONS WHOSE WEIGHTING COEFFICIENTS ARE ASSUMED PIECEWISE CONSTANT, BUT OTHERWISE COMPLETELY UNKNOWN. THIS FUNCTION IS THEN USED TO DESIGN A "DISTURBANCE OBSERVER" AND THE CONTROLLER NECESSARY TO COUNTER THE DISTURBANE. THE PRIMARY OBJECTIVES OF THIS EFFORT WILL BE: 1. TO CHARACTERIZE TYPICAL RADOME BORESIGHT ERRORS FOR USE IN A DIGITAL MODEL. 2. TO DEVELOP A SIMPLIFIED MISSILE INTERCEPT SIMULATION INCLUDING RADOME BORESIGHT ERRORS. 3. TO DETERMINE AN APPROPRIATE SET OF FUNCTIONS TO DESCRIBE TYPICAL RADOME BORESIGHT ERRORS IN THE TIME DOMAIN. 4. TO DETERMINE THE MODIFICATIONS TO THE CONTROL THEORY REQUIRED TO APPLY IT TO THE RADOME BORESIGHT ERROR PROBLEM.
