Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
An augmented tracking apparatus comprising in combination a radar sensor to provide range data an electro-optical sensor to provide angle data an inertial platform to provide inertial frame of reference data, said inertial platform sensing any change in aircraft attitude from said inertial frame of reference and providing attitude data corresponding to said change, and, a computing means connected to said radar sensor and said electro-critical sensor to respectively receive said range data and said angle data, said computing means connected to said inertial platform to receive said inertial frame of reference data and said attitude data, said computing means processing said range, angle and attitude data to provide target state data, said computing means providing pointing commands to said electro-optical sensor, said electro-optical sensor responding to said pointing commands to scan a preselected area about the predicted target position said electro-optical sensor being a non-imaging electro-optical sensor.
Claim 2
Dependent Claim
