人们正在努力减轻频谱拥挤的严重影响。一种这样的频谱工程努力旨在应用波形多样性来使雷达能够避免干扰并调整其频谱利用率。这种方法取决于波形适应和优化，需要准确了解硬件引起的失真。然而，天线和阵列的失真效应常常被忽视。在本文中，超宽带（UWB）天线表征技术应用于雷达开槽波导阵列，以说明这些角度依赖的失真效果，即使是非UWB天线。利用硬件引起的失真进行波形自适应和优化可以增加系统定向共享频谱的能力。
There is an intense effort underway to mitigate the acute effects of spectral crowding. One such spectrum engineering effort seeks to apply waveform diversity to enable radars to avoid interference and adapt their spectral utilization. This approach hinges on waveform adaptation and optimization that requires accurate knowledge of hardware induced distortions. However, the distortion effects of antennas and arrays are often overlooked. In this paper, Ultra Wideband (UWB) antenna characterization techniques are applied to a radar slotted waveguide array to illustrate these angle dependent distortion effects even for non-UWB antennas. Utilizing hardware induced distortion for waveform adaptation and optimization could increase the ability of systems to directionally share spectrum.
