Research Abstract

We study on the Super-Resolution Direction of Arrival (DOA) Estimation Method Based on Array Interpolation and Adaptive Signal Processing Technique. DOA estimation accuracy is improved by applying spatial smoothing-like preprocessing to array steering vector. Furthermore, we newly proposed a novel blind calibration method of array antenna using dummy array elements.
