摘要

针对毛刺的实时检测校正需求,提出一种基于滤波和预定义阈值检测的干涉数据毛刺实时检测校正方法,并给出了基于现场可编程门阵列的硬件实现。在使用较少硬件资源的情况下,所提方法可实现较高的检测精度,能有效检测出干涉数据中央条纹区可能存在的毛刺,可满足星上数据等实时处理的应用需求。

Abstract

In this study, a detection and correction method for interferogram spikes is proposed based on filtering and predefined threshold detection to satisfy the requirement of real-time spike detection and correction. We present the algorithm hardware implementation based on a field-programmable gate array. In case of less hardware resources, the detection and correction algorithm achieves high detection accuracy, especially for the spikes of the central fringe of interferogram. The algorithm proposed in this study can be used for real-time on-board interferometric data processing.
