An efficient and secure use of the electromagnetic spectrum by different telecommunications and radar systems represents, today, a focal research point, as the coexistence of different radio-frequency sources at the same time and in the same frequency band requires the solution of a non-trivial interference problem. Normally, this is addressed with diversity in frequency, space, time, polarization, or code. In some radar applications, a secure use of the spectrum calls for the design of a set of transmitted waveforms highly resilient to interception and exploitation, i.e., with low probability of intercept/exploitation capability. In this frame, the noise radar technology (NRT) transmits noise-like waveforms and uses correlation processing of radar echoes for their optimal reception. After a review of the NRT as developed in the last decades, the aim of this paper is to show that NRT can represent a valid solution to the aforesaid problems.

不同电信和雷达系统对电磁频谱的有效和安全使用是当今研究的重点，因为不同射频源在同一时间和同一频段内共存需要解决非微不足道的干扰问题。通常，这是通过频率、空间、时间、极化或代码的多样性来解决的。在一些雷达应用中，频谱的安全使用要求设计一组对拦截和利用具有高度弹性的发射波形，即具有低拦截/利用能力的概率。在此框架中，噪声雷达技术 (NRT) 传输类似噪声的波形，并使用雷达回波的相关处理来实现最佳接收。在回顾了过去几十年发展起来的 NRT 之后，
