论文摘要
本文提出了一种使用多色调正弦频率调制（MTSFM）波形模型的波形自动/互相关函数（ACF/CCF）属性的波形系列的方法。 MTSFM波形的调制函数使用傅立叶系列扩展表示。傅立叶系数被用作一组离散参数，可以修改以优化波形家族的属性。波形的ACF/CCF属性利用多目标优化问题进行了优化。每个目标函数都被加权以强调低ACF或CCF SIDELOBES。除了专门设计的ACF/CCF属性外，所得优化的MTSFM波形每个都具有类似Thumbtack的歧义函数。最重要的是，由此产生的MTSFM波形家族具有理想的低峰值功率比（PAPR）和高光谱效率（SE），使其非常适合在实用的雷达发射器上进行传输。
This paper presents a method for generating a family of waveforms with low in-band Auto/Cross-Correlation Function (ACF/CCF) properties using the Multi-Tone Sinusoidal Frequency Modulated (MTSFM) waveform model. The MTSFM waveform's modulation function is represented using a Fourier series expansion. The Fourier coefficients are utilized as a set of discrete parameters that can be modified to optimize the waveform family's properties. The waveforms' ACF/CCF properties are optimized utilizing a multi-objective optimization problem. Each objective function is weighted to place emphasis on either low ACF or CCF sidelobes. The resulting optimized MTSFM waveforms each possess a thumbtack-like Ambiguity Function in addition to the specifically designed ACF/CCF properties. Most importantly, the resulting MTSFM waveform families possess both ideally low Peak-to-Average Power Ratios (PAPR) and high Spectral Efficiency (SE) making them well suited for transmission on practical radar transmitters.
