Paper Abstract

We investigate a new signal model based on the wavelet packet representation to achieve high resolution beam-forming. With a properly selected signal model, we perform a robust iterative algorithm to extrapolate the data outside of the observation interval and, therefore, increase the resolution of the beam patterns for a 1-D linear array. The wavelet packet sign model is particularly attractive in representing nonstationary signals such as the chirp signal. The superior performance of the resulting beamformer is demonstrated by numerical experiments.
