INVESTIGATION OF ACTIVE DOPPLER VELOCITY SENSOR

A study program is directed toward the advance ment of the state-of- the-art of doppler naviga tion radar techniques to meet the high speed, high altitude requirements of an aerospace ve hicle. Flight testing of the manual spectral compression system is reported, with band-width compression ratios of the order of 10 to 1 being achieved. The preliminary development of the Computer and Control unit was completed, and fabrication of the flyable model was essentially completed. The Computer and Control unit was designed to evaluate the two types of velocity determination modulation slope dependent and modulation slope independent.
