Analysis And Simulation Of Remote Sensor Radiance Under Dawn-Dusk Illumination Conditions

Visible remote sensors generally conduct imaging missions in the morning or afternoon ( local time), rarely under dawn-dusk illumination conditions. As the developing of imaging technology, observation are performed under dawn-dusk illumination conditions or night-time in use of low light level imaging, which extends operating time of visible remote sensors substantially.It is complicated of illumination conditions ranging from full sunlight in day-time to quarter moon in night-time, which means that remote sensors need large dynamic range. As the reference of sensors designing and ground image processing, the behavior of remote sensor radiance during satellite running time should be researched for better performance of the sensors.The theory of remote sensor radiance simulating was described, and the simulation process was introduced. After the analysis of simulation results, it is got the features of the change in remote sensors radiance under dawn-dusk illumination conditions or night-time.
