The linear frequency modulation (LFM) signals are employed as transmitted waveforms. Based on the sensed statistics of the target and clutter-plus-noise, assuming the LFM waveforms transmitted at different transmitters can have different starting frequencies and bandwidths, these waveform parameters are designed to maximize the signal-to-clutter-plus-noise ratio at the receiver of the cognitive MIMO radar system. The constraints of the allowable range of operating frequency and total transmit energy are considered. We show that in the tested examples, the designed waveforms are nonorthogonal which leads to superior performance compared with that of the frequency spread LFM waveforms commonly used in the traditional MIMO radar systems.<\/jats:p>","DOI":"10.1186\/1687-6180-2014-89","type":"journal-article","created":{"date-parts":[[2014,6,12]],"date-time":"2014-06-12T09:06:34Z","timestamp":1402563994000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["LFM-based waveform design for cognitive MIMO radar with constrained bandwidth"],"prefix":"10.1186","volume":"2014","author":[{"given":"Shuangling","family":"Wang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zishu","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2014,6,12]]},"reference":[{"issue":"11","key":"651_CR1","doi-asserted-by":"publisher","first-page":"5822","DOI":"10.1109\/TIT.2010.2068930","volume":"56","author":"A Aubry","year":"2010","unstructured":"Aubry A, Lops M, Tulino AM, Venturino L: On MIMO detection under non-Gaussian target scattering.
