New method of ground testing and calibration for infrared earth sensor

Ground of testing and calibration for infrared earth sensor is very important during the RD process of infrared Earth sensor. In order to shorten the development cycle of infrared Earth sensor and improve the precision of testing, a new method of ground testing and calibration for infrared Earth sensor is proposed, and the new equipment which can apply to the system of ground testing and calibration is designed. The equipment used electrical signal source of earth-wave to simulate real infrared radiation, and achieved ground signal of testing and calibration for infrared earth sensor by using the electrical detector equipment and the data system of acquisition and process. The testing results show that the method and equipment can achieve the ground of testing and calibration and improve the test of precision and efficiency.
