摘要
规划空天地多传感器协同观测是综合监测地理环境的首要步骤,其核心是计算出空天地不同传感器组合的观测能力.当前,随着地理环境观测任务的日益复杂,传感器需求者未能有效计算空天地多传感器观测能力,导致无法制定高效的观测规划方案.针对该问题,本文提出了空天地多传感器观测能力计算方法,其核心是构建观测能力满足度函数,按需迭代地计算基础关联、优化关联与增补关联三个步骤的观测能力,求解出满足特定观测效益目标的多传感器协同观测方案.选取武汉1+8城市群地表环境土壤湿度观测规划作为实验场景,以观测能力满足度达90％为观测效益目标,通过按需迭代地计算多传感器观测能力,最终求解出观测能力满足度达90.86％的多观测协同方案,为地表环境土壤湿度监测提供了及时、可靠的观测协同规划依据.
Abstract
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.
