Abstract

An embodiment of the invention provides a radiation contrast-based satellite detection performance assessment method. The method comprises the steps of converting an electron flux output by a detectorinto an equivalent object, and calculating an image signal-noise ratio in combination with system noises according to the equivalent object; and according to the image signal-noise ratio, performingcalculation to obtain a minimum distinguishable radiation contrast model, and by adopting the minimum distinguishable radiation contrast model, assessing satellite detection performance. Embodiments of the invention furthermore provide a radiation contrast-based satellite detection performance assessment apparatus, an active interaction apparatus and a non transient readable memory, which are usedfor realizing the method. The satellite detection performance can be effectively assessed under the condition of no human eye intervention.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of satellite performance evaluation, and in particular to a radiation contrast-based satellite detection performance evaluation method, device and memory. Background technique [0002] In recent years, with the improvement of my country's space-based remote sensing equipment system and the accumulation of massive optical remote sensing data, users' application of remote sensing images has continued to deepen, making optical remote sensing satellite technology widely developed and applied in many fields. Especially in the field of military applications, optical remote sensing satellites can be called the eyes of modern warfare, and remote sensing images generated by satellites have become one of the main sources of information for ground forces. Therefore, the detection performance evaluation of optical remote sensing satellites has important guiding significance for the design and m...
