The radar output from the primary radar signal processing is represented as a 2D image composed from echoes of the targets and noise background. The Frequency Modulated Interrupted Continuous Wave (FMICW) radar PCDR35 (Portable Cloud Doppler Radar at the frequency 35.4 GHz) was used. Presently, the processing is realized via a National Instruments industrial computer. The neural network of the proposed system is using four or five (optional for the user) signal processing steps. These steps are 2D spectrum filtration, thresholding, unification of the target, target area transforming to the rectangular shape (optional step), and target board line detection. The proposed neural network was tested with sets of four cases (100 tests for every case). This neural network provides image processing of the 2D spectrum. The results obtained from this new system are much better than the results of our previous algorithm.<\/jats:p>","DOI":"10.3390\/sym11101308","type":"journal-article","created":{"date-parts":[[2019,10,17]],"date-time":"2019-10-17T11:07:59Z","timestamp":1571310479000},"page":"1308","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Neural Networks Application for Processing of the Data from the FMICW Radars"],"prefix":"10.3390","volume":"11","author":[{"given":"Lubos","family":"Rejfek","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering and Informatics, University of Pardubice, 532 10 Pardubice, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2286-6652","authenticated-orcid":false,"given":"Tan","family":"N.
