Active Error Calibration Based on Correlation and its Implementation Using TMS320C6711

The algorithm of active error calibration based on correlation is important to engineering realization of direction finding. In recent years, there have appeared many direction-finding methods, which have high performance. But these methods are very sensitive to the feature of real system, so array channel must be calibrated. This paper uses the algorithm of active error calibration to calibrate amplitude and phase error when the feature of the system is not satisfactory. The algorithm is implemented on high speed float DSP TMS320C6711 and the good performance and real time implementation is achieved.
