先前的工作已经解决了自适应雷达波形，其可以被设计为在频谱上正交于所接收的带内时变干扰环境。本文介绍了一种不同的自适应波形技术，即一个标准的线性调频波形进行修改，以尽量减少其相邻频带的干扰，其他频谱用户。此外，结果示出为带内和/或相邻频带频谱抑制，以提高雷达性能和最小化对其他频谱用户的干扰，同时保持良好的模糊函数性能。模糊函数绘制为每种情况下显示良好的近似理想的线性调频模糊函数。
Previous work has addressed adaptive radar waveforms that may be designed to be spectrally orthogonal to a received, in-band, time-varying, interference environment. This paper introduces a different adaptive waveform technique whereby a standard LFM waveform is modified to minimize its adjacent-band interference to other spectral users. In addition, results are shown for in-band and/or adjacent-band spectral suppression for improving radar performance and minimizing interference to other spectral users while maintaining good ambiguity function performance. Ambiguity functions are plotted for each case showing good approximation to the ideal LFM ambiguity function.
