Abstract
The relationship between image quality and optical Q is sensitive to the system design parameters such as modulation transfer function (MTF), signal-to-noise ratio (SNR), and ground sampled distance (GSD). In this paper, two concepts about Q and NIIRS for remote sensing imager quality analysis and design are presented, and each part physics mean in model and formula are illustrated separately, the influence of Q on the image quality of remote sensing system is specific analyzed, the system performance of Q = 1 and Q = 2 of remote sensing base on NIIRS are compared, the interaction between remote sensing image quality and Q is obtained based on NIIRS by image simulations and comparing with each other simulation results, the optimum design of remote sensors are mainly discussed. Finally, a method to improve the image quality scale is posed for remote sensing systems, the image quality scale of remote sensing systems can be improved by increasing along-scan sampling. Comparisons with preliminary results show that the interaction between image quality and Q is very sensitive to the system design parameters although more validation experiments are needed.
