基于红外设备外场试验可以获得很多系统参量，提出红外成像系统效应仿真应基于设备外场试验参量进行.分析了红外成像系统的像差效应、离焦效应、空间积分效应和噪声分布，分别就红外成像系统的光学系统效应和探测器效应进行了仿真.结合红外系统试验参量给出了红外成像系统效应仿真结果.

Based on the infrared equipment field test, many system measurement parameters can be obtained。 An effect simulation of infrared imaging system is proposed to be made on the basis of the system measurement parameters. For the infrared imaging system, the aberration effect, defocus effect, space integraling effect and noise distribution were analyzed, and the optic system effect and detector effect were simulated respectively. The result of imaging simulation was given in combinition with the test parameters of infrared system.
