Analyzingand Modeling on Space Environment Effects Equivalence

A novel space environment effects equivalence model used for space optical detection is proposed in this paper. In this model, the effects on the space optical detection system are equivalent to defocus, image motion, vibration and noise. Besides, the equivalent modulation transfer function of the space optical detection system is presented. The proposed model can avoid analyzing so many space influence factors at the same time. Moreover, the model can provide some basis to determine the parameters of the detection system which are difficult to measure. Some numerical simulations are made to test the validity and capability of the proposed model.
