Any undesired signal overlapping the MWR protected frequency bands introduces a bias in the measurements, which can corrupt the retrieved geophysical parameters. This paper presents a literature review of RFI detection and mitigation techniques for microwave radiometry from space. The reviewed techniques are divided between real aperture and aperture synthesis. A discussion and assessment of the application of RFI mitigation techniques is presented for each type of radiometer.<\/jats:p>","DOI":"10.3390\/rs11243042","type":"journal-article","created":{"date-parts":[[2019,12,20]],"date-time":"2019-12-20T03:19:36Z","timestamp":1576811976000},"page":"3042","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["A Review of RFI Mitigation Techniques in Microwave Radiometry"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8500-5534","authenticated-orcid":false,"given":"J.","family":"Querol","sequence":"first","affiliation":[{"name":"Interdisciplinary Centre for Security, Reliability and Trust (SnT), University of Luxembourg, 29 Avenue John F.
