Abstract :
We have introduced MUSIC technique to estimate discrete power angular spectrum in the multi-probe based anechoic chamber setups with power estimation. The MUSIC algorithm presents DoA estimates with high resolution. The power estimates based on DoA estimates match well with the target in the measurements. To improve accuracy and robustness in elevation DoA estimation, a virtual array with large aperture in elevation is suggested in practical measurements.
