论文摘要
解决了满足NTIA RSEC要求的恒定模量（CM）连续波（CM）波形设计。提出了临时投影技术来修改原型波形的光谱以满足NTIA RSEC要求，并保留原始波形歧义函数的“拇指键”属性。周期性的二进制频移键（BFSK），Costas FSK和类似噪声的波形被修改以满足CM和NTIA RSEC要求。介绍的示例表明了光谱修改后果以及提出的技术的效率，用于生成具有拇指tack歧义功能的CM频谱控制波形。
The problem of a constant modulus (CM) continuous wave (CW) waveform design with the thumb-tack ambiguity function that meets the NTIA RSEC requirements is addressed. The ad-hoc and alternating projection techniques are proposed to modify the spectrum of a prototype waveform to meet the NTIA RSEC requirements, retaining the "thumb-tack" property of the original waveform ambiguity function. Periodic binary frequency shift keying (BFSK), Costas FSK, and noise-like waveforms are modified to meet CM and NTIA RSEC requirements. Introduced examples demonstrate the spectrum modification consequences and the proposed technique's efficiency for generating the CM spectrum-controlled waveforms with the thumb-tack ambiguity function.
