RT Journal Article SR 00 ID 10.3390/s150100422 A1 López Rodríguez, Patricia A1 Escot Bocanegra, David A1 Fernández Recio, Raúl A1 Bravo Muñoz, Ignacio T1 Non-Cooperative target recognition by means of singular value decomposition applied to radar high resolution range profiles JF Sensors YR 2015 FD 2015 VO 15 IS 1 SP 422 OP 439 K1 NCTI; ATR; range profiles; SVD; synthetic database; actual measurements AB Radar high resolution range profiles are widely used among the target recognition community for the detection and identification of flying targets. In this paper, singular value decomposition is applied to extract the relevant information and to model each aircraft as a subspace. The identification algorithm is based on angle between subspaces and takes place in a transformed domain. In order to have a wide database of radar signatures and evaluate the performance, simulated range profiles are used as the recognition database while the test samples comprise data of actual range profiles collected in a measurement campaign. Thanks to the modeling of aircraft as subspaces only the valuable information of each target is used in the recognition process. Thus, one of the main advantages of using singular value decomposition, is that it helps to overcome the notable dissimilarities found in the shape and signal-to-noise ratio between actual and simulated profiles due to their difference in nature. Despite these differences, the recognition rates obtained with the algorithm are quite promising. PB MDPI SN 1424-8220 LK http://oa.upm.es/44795/ UL http://www.mdpi.com/1424-8220/15/1/422
