The doppler effects on the Frank polyphase coded waveform are studied by taking the waveform correlation function for many different values of doppler phase shift as related to a radar return signal. A doppler model, ambiguity function, and detection system are defined prior to the doppler study. Conclusions based principally on graphical observations of the detected waveform as well as deductive reasoning from mathematical formulation are stated in an orderly ...
The Mobile Navigation Laboratory (MNL) preliminary design task consisted of the system definition and design of an extremely flexible and general purpose instrumented vehicle for use in conducting navigation system development and evaluation tests. A forty-foot, single-compartment, 3-axle coach configuration was selected as the optimum vehicle available. A dual-computer data processing system physically separating the functions of reference navigation and test implementation was selected as the configuration most likely to ...
The overall objective of this program was to improve the U.S. Air Force's weapon delivery and navigation capability through a more accurate and reliable determination of vehicle velocity especially designed for optimal integration into an aircraft reference system. The specific objective of the study was to investigate the feasibility of developing a doppler velocity sensor that provides a three-axis velocity estimate with 0.05 percent accuracy while requiring only 0.5 second ...
The report describes the Pulse Doppler Modification installed on AN/FPS-16 radars, S/N 13 and S/N 14, located on the Pacific Missile Range. Part 1 of the report provides a review of the engineering design of the equipment. Part 2 describes the acceptance testing of the equipment. (Author)
Section one of the report contains the results of systems analysis of the Porcupine radar system and of several data processing techniques. Section two contains documentation for data processing instrumentation implemented during the period of the report. (Author)
