Spectrally-constrained sequences (SCSs) with good correlation properties, and low spectral power under the spectral constraint have found many practical applications in communication, and radar systems operating over non-contiguous carriers or frequency slots. In this letter, a construction of single-channel spectrally-null-constrained sequence (SNCS) families with good correlation is proposed. Following the proposed construction, a single-channel polyphase SNCS family with period <inline-formula><tex-math notation="LaTeX">$N(N$</tex-math></inline-formula> + 1), and family size <inline-formula><tex-math notation="LaTeX">$(p-1)$</tex-math></inline-formula> can be obtained, which has zero power leakage under the spectral constraint <inline-formula><tex-math notation="LaTeX">$\lbrace 1+a(N+1):a\in \mathbb {Z}_N\rbrace$</tex-math></inline-formula>, where <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula> is an odd integer, and <inline-formula><tex-math notation="LaTeX">$p$</tex-math></inline-formula> is the minimum prime factor of <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula>. Note that the maximum periodic correlation magnitude of the derived single-channel SNCS family is <inline-formula><tex-math notation="LaTeX">$(N+1)$</tex-math></inline-formula>, which asymptotically achieves the correlation lower bound as <inline-formula><tex-math notation="LaTeX">$p$</tex-math></inline-formula> increasing.
