In this chapter, we apply maximum likelihood (ML) estimation methods to estimate the direction of arrival (DOA), or angle of arrival (AOA), of one or more signal sources, using data received by the elements of an N-element antenna array. The Cramer-Rao (CR) lower bound on angle estimation error is derived under several different signal assumptions. The CR bound helps determine system performance versus signal-to-noise ratio (SNR) and array size.
