基于先验信息的分布式星载单基线SAR/ATI方法

Distributed Spaceborne Single Baseline SAR/ATI Based on a Prior Information

在综述了分布式星载SAR/ATI技术的基础上,阐述了单基线SAR/ATI技术的原理和杂波、噪声对检测、测速性能的影响,给出了一种基于先验信息的单基线SAR/ATI检测和测速方法,最后基于多功能的天基雷达仿真系统进行了仿真实验和性能分析。

Based on an overview of the distributed spacebome SAR/ATI, this paper describes the principle of SAR/ATI and the impact of clutter and noise to the SAR/ATI performance, and proposes a new SAR/ATI method based on a priori information. Based on the multifunctional spacebome radar simulator, simulation experiment and performance analysis are carried out to verify the effectiveness of the inethod.
