直扩宽带通信较之常规窄带通信具有较好的反侦察和抗干扰能力,因而日渐被广泛用于军事通信领域。但采用当前先进侦察技术,可对直扩通信进行检测,并可据此对其实施有效的拦阻式干扰。本文提出噪声通信,以真正噪声作为信号载体,提出两种噪声通信体制,移频噪声通信和延时噪声通信,并阐述其基本工作原理,重点研究其具有更好的反侦察和抗干扰效能。由于噪声通信的载体和周围噪声同为噪声,极难从中检测出噪声通信而具有极佳的反侦察能力。独立噪声间互不相关,很难对其实施相关干扰,因而使噪声通信具有优越的抗干扰性能。由此,噪声通信具有更高层次的“隐身”能力,可望应用于极其重要的军事通信领域。
Straight-spread wideband communication has better anti-reconnaissance and anti-jamming capabilities than conventional narrowband communications and is therefore increasingly used in military communications. However, the use of the current state-of-the-art reconnaissance technology enables the detection of DS-DS communications and the effective implementation of blockade-based interference. In this paper, we propose the noise communication, and use the real noise as the signal carrier. We propose two kinds of noise communication system, frequency shift noise communication and time delay noise communication. The basic working principle of the system is described. The anti-reconnaissance and anti-jamming performance are emphasized. Since the carrier of the noise communication and the surrounding noise are both noise, it is extremely difficult to detect the noise communication therefrom and have excellent anti-reconnaissance capability. Independent noise is not related to each other, it is difficult to implement related interference, thus making noise communication has superior anti-jamming performance. As a result, noise communication has a higher level of “stealth” capability and is expected to be applied in the field of extremely important military communications.
