This paper proposed a new remote sensing observation capability evaluation model (RSOCE) based on analytic hierarchy process to quantitatively evaluate the capability of multi-satellite cooperative remote sensing observation. The analytic hierarchical process model is a combination of qualitative and quantitative analysis of systematic decision analysis method. According to the objective of the remote sensing cooperative observation mission, we decompose the complex problem into several levels and a number of factors, compare and calculate various factors in pairs, and obtain the combination weights of different schemes. The model can be used to evaluate the observation capability of resource satellites. Taking the optical remote sensing satellites, such as China’s resource satellite series and GF-4, as examples, this paper verifies and evaluates the model for three typical tasks: point target observation, regional target observation, and moving target continuous observation. The results show that the model can provide quantitative reference and model support for comprehensive evaluation of the collaborative observation capability of remote sensing satellites.

Evaluation Model of Remote Sensing Satellites Cooperative Observation Capability

China has done much to promote Earth observation to serve civilian applications by developing its own satellite and adopting international satellite resources. Through the effort of scientists and engineers in the past over twenty years, a lot of achievements of remote sensing applications in many fields have been obtained with the support of the Chinese government. Some of the applications are close to operational which is working for the development of the economic construction of China. But to fully serve the development of the economic construction there is still much effort needed to be done to bridge the knowledge gap between standard products and information in order to provide the consumers with valuable information in an operational way on a daily basis.

The progress of China Earth observation from space and the economy

A cooperation earth observation model constituted by two SAR satellites and one optical remote sensing satellite is proposed. In this model, the optical remote sensing satellite orbit plane locates in the middle of two SAR satellites, and two SAR satellites observe the same ground area from two sides of the optical satellite respectively. However, because of the influence of earth curvature, not only orbits of three satellites must meet certain conditions to realize the cooperation goal that is to observing the same ground area simultaneously, but also SAR view-angle must be adjusted with optical satellite movement in its orbit. So here the cooperation model of two SAR satellites and one optical remote sensing satellite is discusses and the explicit expressions of simultaneous observable conditions are deduced. Then, the calculation method of SAR view-angles is presented. At last, computer simulation results are employed to confirm the mathematical analysis.
