- Provided are an array antenna apparatus using spatial power spectrum combining and a method of controlling the same. The array antenna apparatus includes a uniform linear array antenna module including antennas which are uniformly and linearly arranged, an array antenna determiner configured to select sub-array antennas arranged at a first distance and sub-array antennas arranged at a second distance from the array antennas in the uniform linear array antenna module in order to derive spatial spectrum components from the uniform linear array antenna module, a spatial spectrum component deriver configured to separately derive spatial power spectrum components from signals received through the selected sub-array antennas selected by the array antenna determiner, and an azimuth calculator configured to calculate an azimuth by performing a calculation with a first spatial spectrum component and a second spatial spectrum component which are separately derived.
