| 摘 要： | 从G倾斜功率谱和倾斜跟踪残余误差两个方面分析了大气湍流外尺度对倾斜跟踪系统跟踪精度的影响。详细推导了G倾斜功率谱以及倾斜跟踪残差与大气湍流外尺度的函数关系式。数值计算结果表明大气湍流外尺度对G倾斜功率谱以及倾斜跟踪残余误差的低频段影响较大,而对高频段的影响可以忽略不计。

| Abstract: | The effect of outer scale of atomospheric turbulence on tracking precision of tilted tracking system is studied by considering G-tilt power spectrum and the residual variance of tilted tracking system.The G-tilt power spectrum and the residual variance of tilted tracking as functions of the outer scale of turbulence are deduced theoretically.The numerical results show that outer scale of turbulence has great effect on G-tilt power spectrum and residual variance of tilted tracking at low frequency but almost has no effect on the high frequency. |
