摘　　要：针对环境减灾二号A/B卫星有效载荷类型多、数据量大、各载荷成像约束不同等特点,根据多用户对图像质量、数据需求量、获取时效性的应用需求,设计了环境减灾二号A/B卫星常规成像模式、应急成像模式、特殊成像模式等各类成像模式,并进行了说明。在轨测试结果表明:环境减灾二号A/B卫星成像模式设计正确、合理。经卫星成像效能分析,两颗卫星两天时间内可对全国陆地区域进行覆盖性观测,并可对全球南北纬80°内任一目标进行观测。此文可为后续光学遥感卫星成像模式设计提供参考。According to the characteristics of multi-payload types,large amount of data and different imaging constraints of each payload of HJ-2A/B satellites,and based on the application requirements of multi-user for image quality,data demand and acquisition timeliness,various imaging modes such as conventional imaging mode,emergency imaging mode and special imaging mode are designed and discussed.The on-orbit test results show that the design of imaging mode for HJ-2A/B satellites is correct and logical.Through the analysis of satellite imaging efficiency,the two satellites can observe the coverage of the national land area and any target within 80°of the global north-south latitude in two days.This paper can provide reference for the design of imaging mode of optical remote sensing satellite.
