    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1467 KB)

    35 w of power was produced at 132 mc using four transistor amplifier modules in the final stage, combined by a hybrid network. The use of the hybrid system permits summing of signals with a high degree of isolation between the amplifier modules. This permits operation of the amplifier modules to their full power capacity without requiring a match of device characteristics or equal power-sharing ca... View full abstract»

    The Naval Space Surveillance System is a multistatic cw radar system using the principle of the radio interferometer. Satellites are located in space by measuring the direction cosines of the reflected radio energy and triangulating from two or more receiving sites. Since the direction cosines are determined by electronically measuring the electrical phase difference between pairs of antennas, it ... View full abstract»
