Detailed Data Analysis of Echo I, Echo II and Moon Reflected Signals. Volume 3. Measurement of Relative Phase Differences Between Elements of an Adaptively Phased Array

摘要

The report described a method for measuring the relative phase differences between elements of an adaptively-phased array. A discussion is presented on the need for such measurements, especially from the viewpoints of adaptively phasing on array of transmitting antennas, and the method of measurement is described. The instrumentation of a 27 mc/sec phase detector is given in detail, including an accurate circuit diagram. The experimental results of calibrating the instrument are included. Data obtained on actual Echo-reflected signals show that the adaptively-phased array elements were performing their cohering function. (Author)
