Abstract

The paper describes a method for constructing and developing algorithms for compressing hyperspectral aerospace images (AI) of hardware implementation for subsequent use in remote sensing Systems (RSS). The developed compression methods based on differential and discrete transformations are proposed as compression algorithms necessary for reducing the amount of transmitted information. The paper considers a method for developing compression algorithms, which is used to develop an adaptive algorithm for compressing hyperspectral AI using programmable devices. Studies have shown that the proposed algorithms have sufficient efficiency for use and can be applied on Board spacecraft when transmitting hyperspectral remote sensing data in conditions of limited buffer memory capacity and communication channel bandwidth.

Summary

Introduction

Hyperspectral remote sensing AI is important for observing and studying changes in the Earth's surface, monitoring natural resources and the consequences of emergencies, etc. The development of software systems for transmitting such data is an urgent task In solving this problem, there are two areas of research: the development of compression algorithms used in ground-based remote sensing data reception and processing centers; and those used on Board SPACECRAFT. The problems listed above that arise when developing software systems that are applicable on Board the SPACECRAFT give rise to the following range of requirements for the compression algorithm:. Well-known algorithms based on truncated block encoding [1], differential pulse modulation [1], discrete cosine transform [2], and discrete wavelet transform [2] exist and are used for compressing hyperspectral AI These algorithms on the SC bot, which require large computing resources, do not always meet the above compression requirements. In this paper, we propose to consider a method for developing algorithms for compressing hyperspectral AI that meet these requirements
