Abstract :
A simple and novel method for estimating the power azimuth spectrum (PAS) is presented in this letter. Analysis shows that the expected power received by the directional antenna can be expressed as the integral of the PAS multiplied by the antenna pattern. Therefore, the PAS can be estimated by conducting azimuth-scanning power measurements with directional antenna and solving the integral equation. The influence of the antenna directivity on estimation is also analyzed.
