摘要
基于双激光器测量机翼弹性变形量的理论模型,应用误差分析理论,分析了飞机在飞行过程中双激光器测量方法的误差。以激光器的原始测距误差为出发点,依据误差传递公式,分析了测量机翼变形量的绝对误差和相对误差,并给出了计算仿真结果和相应的图形。研究结果对机载毫米波综合孔径成像系统的图像校正和相位补偿、机载导弹挂飞试验等具有及其重要的应用价值。
Based on the theoretical model of real-time measuring elastic deformation of a wing during the flutter by using two-laser range and using error analysis theory, error about the measurement of deformation of wing during flutter was analyzed. According to original laser measure error and error analysis transfer expressions, calculations about absolute errors and relative errors of the measuring deformation of wing were performed. And the calculation results and picture are acquired. The resuits is useful and have important value for some problems such as phase compensation of airborne millimeter synthetic aperture imaging system, as well as tests of flying: with missiles and so on.
