摘要
Abstract
Due to the variation of optical axis of ship-borne unified C-band TT&C system(UCB),the pointing error of optical axis cannot be corrected accurately by the radar's zero position of the calibration at the dock,the axis error such as the optical-mechanical axis non-parallelism,and the error modifying coef-ficients of electric axis calibrated with optic axis are unavailable.To solve above problem,through analyzing calibration and correction method of radar axis error,an alterative method is proposed to calibrate the radar shafting error dynamically by using theodolite,along with electrical axis to get optical-electrical axis non-parallelism parameter of UCB.The corresponding model is given and the processing results of real data in-dicate that the parameters marked by alternative method are accurate and reasonable,and the accuracy of the data is improved effectively.关键词
