论文摘要
反向预测算法（BPA）是一种时域匹配的滤波技术，以形成合成孔径雷达（SAR）图像。为了产生高质量的BPA图像，必须知道雷达平台的精确导航数据。任何位置，速度或态度的错误都会导致形成不当的图像，由于转移，模糊和失真而损坏。本文开发了分析表达式，以表征导航错误与图像形成错误之间的关系。这些分析表达式通过模拟图像形成和真实数据图像形成验证。
The Back-Projection Algorithm (BPA) is a time domain matched filtering technique to form synthetic aperture radar (SAR) images. To produce high quality BPA images, precise navigation data for the radar platform must be known. Any error in position, velocity, or attitude results in improperly formed images corrupted by shifting, blurring, and distortion. This paper develops analytical expressions that characterize the relationship between navigation errors and image formation errors. These analytical expressions are verified via simulated image formation and real data image formation.
