摘　　要：带有红外成像探测系统的飞行器在大气层内高速飞行时,光学头罩与大气层之间发生剧烈的相互作用,产生气动光学效应。该效应将引起像偏移、像模糊、像抖动,使得红外成像探测系统对目标的成像探测威力下降、探测精度降低。研究了高速动平台下气动光学效应的内涵及其对红外成像探测系统探测威力、探测精度的影响机理,对典型飞行状态下产生的气动光学效应进行了数学仿真计算,得到了仿真计算结果,并对仿真结果进行了分析。As a high-speed aero craft carrying an infrared imaging detecting system flies in the atmos- phere, the aero-optical effect is incurred by the intense interaction between its optical dome and the at- mosphere, which causes image shift, blur and jitter, and leads to the degradation of detection power and accuracy to the target. The connotation of the aero-optical effect in high-speed platform and its influen- cing mechanism on the detection power and accuracy of the infrared imaging detecting system are de- scribed. The aero-optical effects at the typical flight condition are numerically simulated and some simula- tion results are presented. At last, the results of simulation are compared and analyzed.
