The Observation Capability Calculation of Air-Space-Ground Multi-sensors for Comprehensive Monitoring of Geographical Environment
Planning the cooperative observation of air-space-ground multi-sensors is the first step of comprehensive moni-toring of geographical environment,the core of which is to cal-culate the observation ability of different combinations of sen-sors in air-space-ground. At present,with the increasing com-plexity of geographical environment observation tasks,sensor demanders cannot effectively calculate the observation capabil-ity of multi-sensor in air-space-ground,resulting in the inabili-ty to develop efficient observation planning schemes. To solve this problem,this paper proposes a method for calculat-ing the observation capability of air-space-ground multi-sen-sor. The core of this method is to construct the observation ca-pability satisfaction function,and iteratively calculate the ob-servation capability of three steps;basic association,opti-mized association and additional association,in order to solve a multi-sensor collaborative observation scheme that meets the specific observation benefit objectives. The soil moisture monitoring of the surface environment in Wuhan 1+8 urban agglomeration was selected as the experimental scene,and the observation capability satisfaction of 90% was taken as the observation benefit target. The multi-sensor observation capa-bility was calculated iteratively according to the needs,and the multi-observation cooperative scheme with the observa-tion capability satisfaction of 90.86% was finally solved. It provides a timely and reliable basis for cooperative planning of soil moisture monitoring in surface environment.
