The results were compared with the backscattering cross section of similar cases, using analytical method validation from literature. The objective of this research was to look into the possibility of replacing analytical methods with the RHESA in volume scattering calculations, and integrating it into modelling the backscattering of layers of dense media for microwave remote sensing in vegetation; as RHESA provides the freedom to model any shape of scatterer, as opposed to the limited shapes available of scatterers in analytical method models. The results demonstrated a good match, indicating that the RHESA may be a good fit for modelling more complicated media, such as vegetation, in future studies.<\/jats:p>","DOI":"10.3390\/rs14195051","type":"journal-article","created":{"date-parts":[[2022,10,11]],"date-time":"2022-10-11T00:50:01Z","timestamp":1665449401000},"page":"5051","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Backscattering Analysis Utilizing Relaxed Hierarchical Equivalent Source Algorithm (RHESA) for Scatterers in Vegetation Medium"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6847-8591","authenticated-orcid":false,"given":"Syabeela","family":"Syahali","sequence":"first","affiliation":[{"name":"Faculty of Engineering and Technology, Multimedia University, Melaka 75450, Malaysia"}]},{"given":"Hong-Tat","family":"Ewe","sequence":"additional","affiliation":[{"name":"Lee Kong Chian Faculty Engineering and Science, Universiti Tunku Abdul Rahman, Sg.
