Singular value eliminating parameter estimation weight designing method for ultra short base line installation error calibration

The invention relates to a parameter estimation weight designing method for ultra short base line installation error calibration. The parameter estimation weight designing method can be applied to ultra short base line installation error calibration, singular values can be effectively eliminated, and the installation and locating accuracy of an ultra short base line device is accordingly improved. Characteristic matrixes of the singular values are calculated through a coefficient matrix in an ultra short base line installation error calibration observation equation, characteristic values of the singular values are extracted from the characteristic matrixes of the singular values, and whether data corresponding to the characteristic values have singularities or not is judged in this way. A high judgment threshold and a low judgment threshold are set, the characteristic values are quantized to be mapped into singular value eliminating trapezoid weights, and the singular value eliminating trapezoid weights are further combined to form singular value weight eliminating weight matrixes. The weights are led into conventional ultra short base line installation error calibration calculation, influences of the singular values on installation error calibration can be effectively reduced, and the accuracy of calibration calculation can be improved. The parameter estimation weight designing method is suitable for error calibration calculation of ultra short base line installation positional deviations and installation angle deviations.
