Abstract

In this work the inverse transfer function of the measurement room is obtained using a linear and RLS (recursive least-squares algorithm) ADAPTIVE FILTER. At first, an antenna with known pattern (reference antenna) is placed in the test zone to obtain the optimal tap weights of the ADAPTIVE FILTER. Once the filter converges, the learning stage finishes. After that the reference antenna is replaced with the test antenna and its pattern is measured and the data of the measurement is filtered by the optimal tap weights ADAPTIVE FILTER. The filter cancels the stray signals (reflected and scattered signal) and produces the RADIATION PATTERN of the test antenna. This technique is superior to that of others because it has better accuracy and it is less costly.
