Classical radars use deterministic waveforms, such as linear frequency modulated pulses. Noise radars, on the other hand, use random waveforms, or waveforms that resemble random signals. The randomness of the signal provides certain advantages, such as limiting or avoiding range/velocity measurement ambiguity, or better resistance to jamming. This, however, comes at a price of more complicated system architecture and reduced detection range. In this article a comparison of classical deterministic waveform radars and their noise versions is carried out, showing their similarities and differences.

噪声与确定性波形雷达——可能性和局限性

经典雷达使用确定性波形，例如线性调频脉冲。另一方面，噪声雷达使用随机波形或类似于随机信号的波形。信号的随机性提供了某些优势，例如限制或避免距离/速度测量的模糊性，或更好的抗干扰能力。然而，这是以更复杂的系统架构和缩小的检测范围为代价的。在本文中，对经典确定性波形雷达及其噪声版本进行了比较，展示了它们的异同。
