A dual cancelled channel space-time adaptive processing (STAP) scheme is proposed, aiming at reducing the system computational complexity, as well as the amount of required training data, compared to a conventional full array solution. The proposed scheme is shown to yield comparable target detection capability and DOA estimation accuracy with respect to the corresponding full array solution, despite the lower computational cost required. Moreover, it offers increased robustness against adaptivity losses, operating effectively even in the presence of a limited set of training data, as often available in the highly non-homogeneous clutter scenarios experienced in bistatic passive radar. The effectiveness of the proposed scheme and its suitability for passive GMTI are demonstrated against both simulated and experimental data collected by a DVB-T-based multichannel mobile passive radar.<\/jats:p>","DOI":"10.3390\/s21134569","type":"journal-article","created":{"date-parts":[[2021,7,4]],"date-time":"2021-07-04T22:35:22Z","timestamp":1625438122000},"page":"4569","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Dual Cancelled Channel STAP for Target Detection and DOA Estimation in Passive Radar"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5154-8725","authenticated-orcid":false,"given":"Giovanni Paolo","family":"Blasone","sequence":"first","affiliation":[{"name":"Department of Information Engineering, Electronics and Telecommunications (DIET), Sapienza University of Rome, 00184 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6694-7534","authenticated-orcid":false,"given":"Fabiola","family":"Colone","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Electronics and Telecommunications (DIET), Sapienza University of Rome, 00184 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5018-5048","authenticated-orcid":false,"given":"Pierfrancesco","family":"Lombardo","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Electronics and Telecommunications (DIET), Sapienza University of Rome, 00184 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7417-6098","authenticated-orcid":false,"given":"Philipp","family":"Wojaczek","sequence":"additional","affiliation":[{"name":"Fraunhofer Institute for High Frequency Physics and Radar Techniques (FHR), 53343 Wachtberg, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4694-917X","authenticated-orcid":false,"given":"Diego","family":"Cristallini","sequence":"additional","affiliation":[{"name":"Fraunhofer Institute for High Frequency Physics and Radar Techniques (FHR), 53343 Wachtberg, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Melvin, W.L., and Scheer, J.A.
