封面图片为“涪城一号”卫星获取的松花江SAR遥感影像，图中江流蜿蜒曲折，宛如一条银色的丝带镶嵌在广袤的大地上，其独特的纹理与形态，如同国画水墨般渲染交融。“涪城一号”卫星是由绵阳天仪空间科技有限公司研发并运营的国内首颗面向InSAR业务的C波段商业SAR卫星，于2023年6月7日成功发射，拥有聚束、条带、扫描等多种成像模式，最高分辨率可达1 m，最大幅宽可达175 km，定轨精度优于10 cm，能为地质灾害监测、城市安全、应急救灾、基础设施监测等应用提供数据支持。

The SAR remote sensing image of the Songhua River captured by the“Fucheng - 1”satellite

The cover features a SAR remote - sensing image of the Songhua River captured by the “Fucheng - 1” satellite. The river twists and turns, looking like a silver ribbon on the vast land, with textures blending like Chinese ink wash painting. Developed by Spacety Co., Ltd. (Mianyang)，“Fucheng - 1”, China's first C - band commercial SAR satellite for InSAR services, was launched on June 7, 2023. It has imaging modes like Spotlight, StripMap and ScanSAR, with a maximum resolution of 1 m, a maximum swath width of 175 km, and an orbital accuracy better than 10 cm. It can support geohazard monitoring, urban safety, emergency rescue, and infrastructure monitoring.
