Abstract


This thesis mainly solve the double bend under condition of erection of large gradient day linear surface detection radar data processing. Principle of radar antenna detection is by a laser projection light spot target generator, two sets of electronic theodolite intersection measurement, get the sampling points in the 3 d coordinates, and then to the corresponding data processing, in the end of the antenna of the deformation and skin surface processing error. Radar antenna erection conditions, caused by the gravity deformation of the actual face shape deviation theory, the deformation caused by system error; And skin surface processing and solder joint poor contact is the random error of antenna. Data processing of this paper mainly includes: a, realize the conversion of the coordinates of the measured data, measured data from the measurement coordinate system to the design coordinate system; Second, on the surface of the antenna deformation system error; Three, the establishment of the antenna surface model based on neural network, the random error of each point value, take its root mean square with statistical method as the standard deviation, and eventually obtained on the surface of the antenna type surface error value. With the level of state on the surface of the antenna type surface error values are compared to show the data processing method is feasible.
