Purpose The purpose of this paper is to evaluate the detection performance of infrared photoelectric detection system and establish stable tracking platform. Design/methodology/approach This paper puts forward making use of the finite element analysis method to set up the infrared radiation characteristics calculation model of flying target in infrared photoelectric detection system; researches the target optical characteristics based on the target imaging detection theory; sets up the heat balance equation of target’s surface node and gives the calculation method of total radiation intensity of flying target; and deduces the target detection distance calculation function; studies the changed regulation of radiation energy that charge coupled device (CCD) gain comes from target surface infrared heat radiations under different sky background luminance and different target flight attitude. Findings Through calculation and experiment analysis, the results show that when the target’s surface area increases or the target flight velocity is higher, the radiation energy that CCD obtained is higher, which is advantageous to the target stable detection in infrared photoelectric detection system. Originality/value This paper uses the finite element analysis method to set up the infrared radiation characteristics calculation model of flying target and give the calculation and experiment results; those results can provide some data and improve the design method of infrared photoelectric detection system, and it is of value.

Stray Radiation

Analysis and calculation of stray light is important to improve the performance of infrared detection system. In this article, we mainly discussed two sources: earth and atmosphere emission and thermal stray radiation. A method based on Monte Carlo ray-tracing in TracePro is proposed to calculate the irradiance of detector arisen from earth and atmosphere emission. The thermal stray light irradiance on detector can also be obtained by simulation in TracePro.
