Estimating the Mean Square Error in Measuring Bearing by Calculating Phase Mismatch

Аннотация

Abstract—The procedure for estimating the mean square error (MSE) in measuring bearing from a single signal sampling in direction-finding equipment based on digital antenna arrays is considered. An algorithm based on estimating the phase mismatch is proposed. It is shown that this algorithm makes it possible to estimate the MSE in accordance with the lower Kramer–Rao boundary.
