Analysis of visibility of high-altitude balloon on the spectrum by using airborne optoelectronic device
摘要
Abstract
The paper analyzed the characteristics of the environment where the high-altitude balloon and the airborne detector work. By using the atmospheric transporting model (MODTRAN), the paper calculated the background noise intensity under the condition of the same probe point and the different time and the background brightness of the target at the different time. By using the backward Monte Carlo method, the paper calculated the scattering radiance of the high-altitude balloon received at the space-based probe point. After calculating the signal to noise ratio (SNR), the paper made an analysis of the visibility of the target. The results show that, during the airborne detection, with the smaller detecting angle or the greater solar zenith angle of the target, SNR is higher to satisfy the threshold of the detection equipment, which is also beneficial to the choice of spectral bands when the target location and the detecting altitude are both fixed.关键词
