This paper presents a method for generating a family of waveforms with low\nin-band Auto/Cross-Correlation Function (ACF/CCF) properties using the\nMulti-Tone Sinusoidal Frequency Modulated (MTSFM) waveform model. The MTSFM\nwaveform's modulation function is represented using a Fourier series expansion.\nThe Fourier coefficients are utilized as a set of discrete parameters that can\nbe modified to optimize the waveform family's properties. The waveforms'\nACF/CCF properties are optimized utilizing a multi-objective optimization\nproblem. Each objective function is weighted to place emphasis on either low\nACF or CCF sidelobes. The resulting optimized MTSFM waveforms each possess a\nthumbtack-like Ambiguity Function in addition to the specifically designed\nACF/CCF properties. Most importantly, the resulting MTSFM waveform families\npossess both ideally low Peak-to-Average Power Ratios (PAPR) and high Spectral\nEfficiency (SE) making them well suited for transmission on practical radar\ntransmitters.\n
