Multi-carrier waveforms have several advantages over single-carrier waveforms for radar communication. Employing multi-carrier complementary phase-coded (MCPC) waveforms in radar applications has recently attracted significant attention. MCPC radar signals take advantage of orthogonal frequency division multiplexing properties, and several authors have explored the use of MCPC signals and the difficulties associated with their implementation. The sidelobe level and peak-to-mean-envelope-power ratio (PMEPR) are the key issues that must be addressed to improve the performance of radar signals. We propose a scheme that applies pattern-based scaling and geometric progression methods to enhance sidelobe and PMEPR levels in MCPC radar signals. Numerical results demonstrate the improvement of sidelobe and PMEPR levels in the proposed scheme. Additionally, autocorrelations are obtained and analyzed by applying the proposed scheme in extensive simulation experiments.

通过山峰模式和几何级数的融合降低多载波雷达信号中的旁瓣电平

对于雷达通信,多载波波形比单载波波形有几个优点。在雷达应用中采用多载波互补相位编码 (MCPC) 波形最近引起了极大的关注。MCPC 雷达信号利用正交频分复用特性,几位作者已经探索了 MCPC 信号的使用及其实现相关的困难。旁瓣电平和峰均包络功率比 (PMEPR) 是提高雷达信号性能必须解决的关键问题。我们提出了一种应用基于模式的缩放和几何级数方法来增强 MCPC 雷达信号中的旁瓣和 PMEPR 水平的方案。数值结果证明了所提出方案的旁瓣和 PMEPR 水平的改善。此外,
