This report presents the results of a detailed analysis of data collected from January through September 1964 using Echo 1, Echo 11, and the moon as reflectors of S-band signals. Information is presented, in four volumes, signal-to-noise ratio improvement in adaptively phased arrays and the autocorrelation function of signals reflected from Echo 11. (Author).

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).
