ABSTRACT:
The present invention relates to a method and a system for determining the direction of arrival of one or multiple radio or acoustic waves and, more particularly, to such a method and system especially advantageous in situations where the number of available observations is small and/or the available observations are received with low power. The method significantly improves the performance of traditional subspace signal processing algorithms in the low sample size regime. The algorithm is specifically designed to provide consistent estimates even when the observation dimension has the same order of magnitude as the number of observations. This guarantees a good behavior in finite sample size situations, where the number of sensors or antennae and the number of samples have the same order of magnitude or in scenarios where the received signal power is not sufficiently high to guarantee detection via conventional one-dimensional search methods.
