Abstract

Abstract:

Satellite sensor is one of the most important means of earth observation.To effectively select and combine multi-satellite sensors to meet the needs of specific observation tasks,a satellite sensor coverage assessment method based on the principle of maximizing spatio-temporal coverage is proposed.This method selects the sensor with the largest spatial coverage in each observation period to complete the optimum combination of sensors.The satellite sensor coverage evaluation and optimal combination observation system is designed and implemented.The satellite sensor modeling,the definition of the observation subject,the evaluation of the sensor coverage ability and the sensor optimal combination were achieved.Finally,with an experiment of emergency rainfall observation in the lower reaches of the Jinsha River Basin,the practicability of the system was verified.

Key words: satellite sensor, capability evaluation, combined observation, observation capability, spatio-temporal coverage
