摘要	In order to solve the problem of lack of unified evaluation standard and engineering closed-loop for target operating distance calculation model of aerial remote sensing camera in different bands, the research on target operating distance evaluation standard of dual band aerial remote sensing camera and engineering application case analysis were carried out. Firstly, according to the characteristics of aerial remote sensing, the three-dimensional projection transformation relationship of the target is proposed to obtain the equivalent observation size of the target under any observation condition; According to the different radiation imaging characteristics of visible and infrared dual band point target and area target, the target operating range calculation models are established respectively. Then, combined with an engineering application example, the results of different calculation models are analyzed and compared, and the calculation model suitable for long-range squint imaging of aerial remote sensing camera is given. Then, the information extracted from the actual flight image of an aerial remote sensing camera is used to reasonably select the signal to noise ratio(SNR) and modulation threshold in the calculation process of target operating distance, According to the modified threshold, the corresponding operating distance of large ships and tanks under different detection and recognition probabilities of visible light and infrared is analyzed. The analysis results show that when the flight height of the carrier is 18 km, the atmospheric visibility is 15 km and the visible light focal length of the aerial remote sensing camera is not less than 1.5 m, the detection distance of 141 km and 93 km for large ships on the sea and 105 km and 80 km for small targets such as land tanks can be realized with 50% probability; Under the condition that the infrared focal length is not less than 1m, the detection distance of 203 km and the recognition distance of 140 km for large ships on the sea and 44 km and 37 km for small targets such as land tanks can be realized with a 50% probability. The above simulation results are consistent with the reality, and the results of this paper can be better applied to engineering practice. 2022, Science Press. All right reserved.
