Abstract:
In super-resolution direction-finding, array sensor position uncertainties often degrade its performance seriously, thus effective calibration procedure is indispensable. Based on subspace principle, this paper presents a new calibrat ion approach with transmitting signals. The method showns that its convergent rate is fast and directions of calibration signals need not be precisely known. Simulational results prove that, if the error is compensated by using the new method, signal DOAs can be accurately estimated with the modifiedMUltiple SIgnal Classification algorithm.
