Sažetak
To validate the theoretically predicted performance of root based direction finding (DF) algorithms an experimental test bed was assembled covering the 1850- 1910 MHz band. A four- element antenna array with uniform interelement spacing was emulated using variable phase shifters creating what is essentially a decoupled array environment. The array outputs were down converted using standard analogue circuits and fed to a four- channel receiver providing four separate digitized data channels. The data were processed with the Modified Root Pisarenko (MRP) algorithm. The results show that using an equivalent physical array aperture of only 1.5 wavelength the directions of arrival (DOA) in a decoupled array environment can be estimated with errors smaller than 0.010.
