Considered as enhanced Low Probability of Intercept (LPI) radars, they are resilient to interference and jamming and less vulnerable to adversarial exploitation than conventional radars. At its simplest, using a random waveform such as bandpass Gaussian noise as a probing signal provides limited radar performance. After a concise review of a particular noise radar architecture and related correlation processing, this paper justifies the rationale for having synthetic (tailored) noise waveforms and proposes the Combined Spectral Shaping and Peak-to-Average Power Reduction (COSPAR) algorithm, which can be utilized for synthesizing noise-like sequences with a Taylor-shaped spectrum under correlation sidelobe level constraints and assigned Peak-to-Average-Power-Ratio (PAPR). Additionally, the Spectral Kurtosis measure is proposed to evaluate the LPI property of waveforms, and experimental results from field trials are reported.<\/jats:p>","DOI":"10.3390\/rs13122372","type":"journal-article","created":{"date-parts":[[2021,6,17]],"date-time":"2021-06-17T11:20:26Z","timestamp":1623928826000},"page":"2372","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Low-PAPR Waveforms with Shaped Spectrum for Enhanced Low Probability of Intercept Noise Radars"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1839-2340","authenticated-orcid":false,"given":"Kubilay","family":"Savci","sequence":"first","affiliation":[{"name":"Turkish Naval Research Center Command and Department of Electrical and Electronics Engineering, Graduate School of Sciences and Engineering, Koc University, 34450 Istanbul, Turkey"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1805-4640","authenticated-orcid":false,"given":"Gaspare","family":"Galati","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Tor Vergata University and CNIT-Consortium for Telecommunications, 00133 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5318-7265","authenticated-orcid":false,"given":"Gabriele","family":"Pavan","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Tor Vergata University and CNIT-Consortium for Telecommunications, 00133 Rome, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"791","DOI":"10.1049\/iet-rsn.2015.0400","article-title":"Compatibility problems related with pulse-compression, solid-state marine radars","volume":"10","author":"Galati","year":"2016","journal-title":"IET Radar Sonar Navig."},{"key":"ref_2","unstructured":"Kulpa, K.
