One of the manifestations of these changes is crater creation with blowouts of a gas, ice and frozen soil mixture. In this context, dynamics studies of long-term heaving mounds that turn into craters as a result are relevant. A workflow for detecting and assessing anomalous dynamics of heaving mounds in the Arctic regions is proposed. Areas with anomalous increase of ALOS-2 PALSAR-2 synthetic aperture radar (SAR) backscattering intensity are detected in the first stage. These increases take place due to sudden changes in local terrain slopes when the scattering surface (mound slope) turns toward the radar. Radar backscattering intensity also rises due to depolarization at newly formed frost cracks. Validation of the detected anomaly is carried out at the second stage through a comparison of multi-temporal digital elevation models obtained from bistatic radar interferometry TerraSAR-X\/TanDEM-X data. At the final stage, the deformations are assessed within the detected areas using differential SAR interferometry (DInSAR) technique by ALOS-2 PALSAR-2 data. The magnitude of the heaving along the line of sight (LOS) was 22\u201324 cm in the period from January 2019 to January 2020. In general, effectiveness for detecting the perennial heaving mounds and the rate assessment of their increase were demonstrated in the suggested workflow.<\/jats:p>","DOI":"10.3390\/rs15010281","type":"journal-article","created":{"date-parts":[[2023,1,4]],"date-time":"2023-01-04T02:15:42Z","timestamp":1672798542000},"page":"281","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Step-Wise Workflow for SAR Remote Sensing of Perennial Heaving Mound\/Crater on the Yamal Peninsula, Western Siberia"],"prefix":"10.3390","volume":"15","author":[{"given":"Valery","family":"Bondur","sequence":"first","affiliation":[{"name":"AEROCOSMOS Research Institute for Aerospace Monitoring, 105064 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3831-4035","authenticated-orcid":false,"given":"Tumen","family":"Chimitdorzhiev","sequence":"additional","affiliation":[{"name":"AEROCOSMOS Research Institute for Aerospace Monitoring, 105064 Moscow, Russia"},{"name":"Institute of Physical Materials Science of SB RAS, Optical-Microwave Remote Sensing Department, 670047 Ulan-Ude, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0744-714X","authenticated-orcid":false,"given":"Aleksey","family":"Dmitriev","sequence":"additional","affiliation":[{"name":"AEROCOSMOS Research Institute for Aerospace Monitoring, 105064 Moscow, Russia"},{"name":"Institute of Physical Materials Science of SB RAS, Optical-Microwave Remote Sensing Department, 670047 Ulan-Ude, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kizyakov, A., Khomutov, A., Zimin, M., Khairullin, R., Babkina, E., Dvornikov, Y., and Leibman, M.
