3965470	Pulse analyzer for an RF moving target detector Threshold count pulses, the number of which being proportional to the slope of an impedance curve of a radiating antenna in an RF detection system, are counted in a first counter and, upon receipt of a read pulse representing a threshold of impedance, are...	06/22/1976
3952304	Tracking system utilizing Kalman filter concepts A monopulse radar tracking system is disclosed employing four tracking channels, one for each of range, velocity, azimuth and elevation. The two angle channels are referenced directly to antenna coordinates. Each channel is mechanized by a stored program ...	04/20/1976
