Abstract

The parameter estimation of multiple transient signals (waves) impinging on a uniform linear array is addressed. Each transient signal is assumed to be a sum of complex exponentials, arriving at the array from a different direction. The method we use to solve this problem is a novel generalization of the subspace decomposition and matrix pencil approach which has been previously used for processing one-dimensional transient signals. Simulation results show that this method can be near efficient statistically.
