Direction-of-arrival estimation method and system in scenarios with low intensity or small sample size

摘要

Relates to a system and method for determining the arrival direction of the wave or waves in one or more, and more particularly, the present invention, situation strength when receiving observations available low number of observations are available, or less at about the system and a particularly advantageous manner. If the sample size is small, this method significantly improves the performance of the signal processing subspace conventional algorithms. The algorithm is specifically designed dimension of observation even if the size comparable to the number of observations, and to allow for consistent estimation. And in insufficient scenario This number of samples and the number of antennas or sensors to perform reliably detected by the primary search method of conventional strength of the received signal or finite sample size scenarios, is of the same order of magnitude , I seen good behavior surely.
