Abstract

Sensor arrays are frequently used to separate and reconstruct superimposed signals arriving from different directions. This paper studies the effect of model errors, i.e., differences between the assumed and actual array response, on the quality of the reconstructed signals. Model errors are the limiting factor of array performance when the observation time is sufficiently long. In this work we analyze a signal estimation technique which is based on the MUSIC algorithm. Formulas are derived for the Signal-to-Interference and Signal-to-Noise ratios as function of the model errors.
