摘　　要：介绍了一种机载双波段全极化SAR系统。系统具备X和L两种波段分时成像的能力,通过变极化发射与变极化接收获得多极化图像,适应航空环境设计思路,尽可能实现系统的模块化、标准化。系统搭载小型无人机载平台,获得了乡镇院落和林区场景的X/L双波段全极化的图像数据。A dual-band full-polarization airborne SAR system is introduced featuring time-sharing imaging at X and L bands,and multi-polarization images are obtained through variable polarization transmitting and receiving to adapt to the design of aviation environment and to achieve a modular and standard system to a feasible extent.The system is equipped with a miniature unmanned airborne platform,acquiring the dual-band full-polarization images of township courtyards and woodlands.

关 键 词：机载SAR 双波段 全极化
