Existing deconvolution methods such as Wiener filtering handle this degradation problem in the Fourier domain. However, under complex degradation conditions, the Wiener filtering results are not accurate. In this paper, a convolutional neural network (CNN) model is proposed to solve the degradation problem. The deconvolution procedure is defined as a regression problem in the spatial domain that can be solved with deep learning. For the real inverse process of microwave radiometer data, the CNN model has a more powerful reconstruction ability than Wiener filtering due to the multi-layer structure of the CNN, which enables the multiple feature transform of the data. Additionally, the complex degradation factor during the imaging process of a microwave radiometer can be solved with general framework-based learning. Experimental results demonstrated that the CNN model gains about 5 dB at the peak signal-to-noise ratio compared to the Wiener filtering deconvolution method, and can better distinguish the measured data.<\/jats:p>","DOI":"10.3390\/rs10020275","type":"journal-article","created":{"date-parts":[[2018,2,12]],"date-time":"2018-02-12T10:50:38Z","timestamp":1518432638000},"page":"275","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["A Deconvolution Technology of Microwave Radiometer Data Using Convolutional Neural Networks"],"prefix":"10.3390","volume":"10","author":[{"given":"Weidong","family":"Hu","sequence":"first","affiliation":[{"name":"School of Information and Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenlong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information and Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shi","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Information and Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Lv","sequence":"additional","affiliation":[{"name":"School of Information and Electronic Engineering, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dawei","family":"An","sequence":"additional","affiliation":[{"name":"National Satellite Meteorological Center, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8838-4560","authenticated-orcid":false,"given":"Leo","family":"Ligthart","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Delft University of Technology, 2628 CN Delft, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,10]]},"reference":[{"key":"ref_1","unstructured":"Ulaby, F.T., Moore, R.K., and Fung, A.K.
