摘要
珞珈二号01星是我国首颗高分辨率Ka频段SAR(synthetic aperture radar)卫星,它开辟了新的成像频段。该卫星围绕Ka频段新体制、雷达天线方位向电扫的技术特点开展视频SAR等多种模式的设计,以此实现新的应用能力。珞珈二号01星通过平台轻小型设计保障载荷工作能力,卫星平台载荷采取机电热一体化设计、平台电子设备板卡式高集成设计以及高效的MPPT(maximum power point tracking)供电技术等。同时,结合在轨实际应用情况介绍了卫星的能力水平及技术指标实现情况。
Luojia2-01 Satellite is the first high-resolution Ka-band SAR satellite in China,which has opened up a new frequency band for SAR imaging.Based on the new system of Ka-band and the technical characteristics of azimuth electric scanning of radar antenna,video SAR and multiple modes are designed to realize new application capabilities.The lightweight and compact design of the platform ensures the payload operational capability of the satellite.The satellite platform payload adopts an integrated design of mechanical,electrical,and thermal system.The electronic equipment with the board card of the satellite platform uses a highly integrated design and efficient MPPT(maximum power point tracking)power supply technology.Combined with the actual application of the satellite in orbit,the capabilities and technical indicators of the satellite are introduced.
