地震监测雷达卫星系统参数的设计
DESIGN OF SYSTEM PARAMETERS OF EARTHQUAKE MONITORING SAR SATELLITE
【摘要】 初步设计了地震监测雷达卫星的轨道参数,讨论了单颗雷达卫星的参数,以及3颗或4颗卫星组成卫星星座时重访周期的变化情况。
【Abstract】 Due to deformation-observing stations in China are very sparse, acquiring the precursor of seismic deformation field and fault activity information is severely limited. Fortunately, the use of spaceborne synthetic aperture radar interferometry technology developed in recent ten years is not limited by regional factors. So it is very necessary to launch SAR satellite to monitor large-scale deformation field. In this paper, on the basis of some international satellites’ parameters primaril design of home SAR satellite’s orbit parameters is describe.The parameters of single SAR satellite and the variety of cycle of repeat visit when three or four satellites build up satellite constellation are discussed as well.
【Key words】 SAR satellite; orbit parameter; cycle of repeat visit; seismic deformation field; earthquake precursor;
