合成孔径雷达 高分辨率 聚束模式 顶层参数设计 Synthetic Aperture Radar high resolution spotlight mode top-level parameters design
摘要
聚束模式是合成孔径雷达(SAR)的一种比较特殊的工作方式，可以获得普通条带模式难以达到的超高分辨率图像。本文以高分辨率星载聚束SAR 系统顶层参数设计为主要出发点，结合详细的系统设计与仿真分析过程，分析了聚束模式下大距离徙动、脉冲重复频率(PRF)选取、天线方向图设计等多方面的系统设计影响因素，能够为星载聚束SAR 顶层参数设计提供有效参考。
Abstract
Spotlight mode is a special mode of Synthetic Aperture Radar(SAR), which can achieve higher resolution image than the ordinary strip-mode SAR. Starting from the top-level parameters design of high resolution space-borne spotlight SAR system, combining with the detailed analysis of system design and simulation process, many influence factors including long migration distance, Pulse Repetition Frequency(PRF), antenna pattern on spotlight SAR system design are analyzed. This work can provide a reference for space-borne spotlight SAR top-level parameters design.
