运用区域细分方法研究了热释电靶面上获得的目标红外热辐射，并推导了红外电视系统的测温方程，温度方程表明红外电视系统输出信号与目标温度、大气透过率、比辐射率等因素有关，同时给出了相应讨论结果 The subdivision method was used to study the target infrared radiation obtained on the pyroelectric target surface and the temperature measurement equation of the infrared television system was derived. The temperature equation shows that the output signal of the infrared television system, the target temperature, the atmospheric transmittance, the specific radiation Rate and other factors, at the same time gives the corresponding discussion results
