Method for making transmission measurements in a dual-chambered anechoic chamber using spatial averaging

摘要

A method for making transmission measurements in a dual-chambered anechoic chamber used in conjunction with spatial averaging. At selected transmitter antenna positions, measurement are taken at different frequencies. For each transmitter position, a measurement is made with the test device positioned between the apertures, and another without the test device. When all desired measurements have been made, the measurement data are spatially averaged; i.e., the measurements are scaled, summed, and averaged, providing more accurate transmission measurements.
