Bibliometric analysis of scientific production on aerospace technology Terrain Following Radar (1966-2024)

Abstract

Objective: To carry out a bibliometric study of the scientific production on the aerospace technology Terrain Following Radar, in the Web of Science database, from 1966 to 2024, using the RStudio® and VOSviewer® software.

Theoretical framework: It is based on the literature on the evolution of aerospace technologies, with emphasis on Terrain Following Radar and its context in the military sphere.

Method: This research is classified as descriptive and quantitative. Data were collected from the Web of Science database, accessed through the Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, covering the period from 1966 to 2024. For data analysis, the RStudio® and VOSviewer® software were used, as well as the bibliometric packages Bibliometrix and Biblioshiny.

Results and conclusion: A total of 433 documents were identified, with the largest scientific productions on the subject coming from the United States, China, Italy, Germany and France. The year with the most publications was 2021, followed by 2022 and 2023. The most cited sources are IEEE Transactions on Geoscience and Remote Sensing, followed by Remote Sensing. The main keyword co-occurrences include SAR (Synthetic Aperture Radar), remote sensing, radar, InSAR (Interferometric Synthetic Aperture Radar), and interferometry. Regarding co-The authors. between countries, the United States, China and Germany stand out. The most relevant authors on the subject are Liu Y., Li Y. and Li Z. In terms of co-citation between authors, Lee J. S., Ferretti A. and Head J. W. The most cited studies globally in the last ten years are by Xue M. (2000), De Zan F. (2006) and Zhang Z. (2017). It is concluded that this study aims to enhance the knowledge base about the Terrain Following Radar aerospace technology and related fields of study.

Research implications: The main limitation of this research is its restriction to the Web of Science database, where most of the documents were articles. Thus, it would be interesting to adopt a broader approach, which includes other databases, such as Scopus or Google Scholar, in addition to considering different types of publications, such as books and conference proceedings.

Originality/value: This study aims to improve knowledge about aerospace technology

Terrain Following Radar and the related fields of study.
