Paper Title:
Identify Moving Noise with Array Signal and MVDR
  Abstract

Using microphone array and beam-forming is an important technology to identify moving noises sources. Capon minimum variation distortion-less response is used proposed to identify the complex noise sources, where many closely distributed noise sources are located nearby. The algorithm is introduced with detail. The identify results is simulated and analyzed with real running vehicle. Comparing the results between common beam forming and Capon method, it shows the Capon minimum variation distortion-less response method has higher resolution and could identify the complex noise distribution of moving vehicles.
