Abstract :
This paper introduces a new blind calibration algorithm as well as a new remedy procedure for velocity-sensor triads´ mis-orientations. The word “blind” indicates the proposed method requires no priori knowledge of incident sources´ direction-of-arrivals (DOAs), and allows the arrays of velocity-sensor triads to be arbitrarily separated at unknown locations in three-dimensional space. Moreover, the present work is applicable to the arrays of velocity-sensor triads with unknown inter-triad gain and phase deviations. Simulation results verify the efficacy and versatility of this proposed scheme.
