This open access book presents the fundamental methods and applications of GNSS-reflected signal reception processing. On the basis of systematic analysis of GNSS signals, it delves into the typical characteristics of signals after reflection, discussing the software and hardware design of GNSS-reflected signal receivers from different perspectives, including RF reception, IF processing, and extraction of observations. It offers a comprehensive introduction and exploration of ocean remote sensing, land remote sensing, and several new applications (such as airborne moving target detection, river boundary monitoring, and surface water body identification). The content covers a variety of different configuration modes such as shore-based, ground-based, airborne, and satellite-based and also includes two signal processing methods: single-antenna interferometry and dual-antenna cooperative method. The data used in the theoretical modeling and algorithm performance simulation validation are both from experiments conducted by the authors' research team and from experiments carried out with partners, as well as results processed from publicly available datasets domestically and internationally.

This book is suitable for faculty and students in the fields related to satellite navigation (such as electronic communication, radar remote sensing, aerospace, and computer), earth observation, and also serves as a reference book for engineers and scientific management personnel engaged in application research in the fields of oceanography, meteorology, agriculture, water conservancy, and environment studies.

Is open access, which means that you have free and unlimited access Summarizes the progress of GNSS reflection signals for earth observation remote sensing in the last decade Introduces the applications of GNSS reflection signals in air, land, and sea remote sensing Presents the fundamental methods and applications of GNSS-reflected signal reception processing
