摘　　要：针对现有航母起降引导系统下滑道真值测量手段过于复杂的现状,提出一种简单的航母起降引导系统下滑道一致性指示数据产生方法,该方法基于着舰引导雷达测距精度、中线电视测角精度较高的特点,利用着舰引导雷达测距信息和中线电视测角信息进行目标位置解算。采取泰勒级数展开法对非线性方程组线性化,并以着舰引导雷达定位结果作为迭代始值,进行迭代运算求取目标位置。通过仿真实验验证该方法迭代次数较少且收敛,相比着舰引导雷达定位方法,具有更高的定位精度。In accordance with the current situation that there are limited means to get the true value in the process of the cal?ibration of taking?off and landing system,this paper presents a new method to generate the taking?off and landing system slope indicator data. Based on the characterisitics that the ranging information the radar mesures and the angle information the mid?dle line camera mesureds own higher accuracy,the method estimates the position with the ranging information. and the angle information. It chooses the solution by Taylor?Series Estimation to straighten the nonlinear equations,then solves the equa?tions,then obtains the target position by iterative calculation.The simulation result indicates that the iteration constricts and it is less often.Through the comparison with the single radar location, the solution which the paper used owns higher position?lo?cation accuracy.
