Requirements to the accuracy of PAA phase meters

Abstract

The development and application of phased antenna arrays (PAA) require a lot of types of phase characteristics to be measured. As a rule large PAA consists of thousands and ten thousands of modules. For them phase characteristics measurements distinguish by their mass character. To carry put these measurements a lot of phase meters are used. They belongs to PAA, because depending of their purpose, they are he part of PAA as its units or (and) devices of PAA complex.
