Abstract

The problem of construction of ultra-wideband direct chaotic communication devices in the very high frequency and ultra high frequency ranges of radio waves is considered, the features of this range with respect to the propagation of electromagnetic radiation are discussed, and performance potential is evaluated. Experimental direct chaotic transceivers with a working band of 200–450 MHz, their structure, technical implementation, and characteristics are presented. The results of laboratory and field tests of prototypes are given to demonstrate transmission ranges of up to 1.5 km, which correspond to the calculated characteristics.

甚高频和超高频无线电频带中的直接混沌超宽带无线通信

摘要

考虑在无线电波的甚高频和超高频范围内构建超宽带直接混沌通信设备的问题，讨论了该范围关于电磁辐射传播的特征，并评估了性能潜力。介绍了工作频带为 200-450 MHz 的实验性直接混沌收发信机，介绍了它们的结构、技术实现和特性。给出了原型的实验室和现场测试的结果，以证明传输范围可达 1.5 公里，这与计算的特性相对应。
