通信机理之变革,经历了超外差原理,相位相干原理,扩跳原理之三大浪潮。扩跳原理最能抗御敌人的窃获、测向和干扰,是战场通信中求生存的最有效手段。 在声、电、光、磁综合利用的分子电子学之电子战的信息对抗时代,大规模集成电路(LSI)、电荷耦合器件(CCD)、声表面波(SAW)和静磁波(MSW)等新型器件的研制,为解决扩频通信之三大难题开辟了新途径。 本文主要阐述三种新型功能器件在扩频通信机中的应用机理、频段、性能,现状与潜力。特别强调了新型器件之卷积器、相关器与匹配滤波器为基础的扩频通信机的设计思想与制作方法。
The change of communication mechanism has experienced three major tide of super heterodyne principle, phase coherence principle, and spreading principle. The most effective method to survive in the battlefield communication is to expand the principle of jumping to resist the theft, direction finding and interference of the enemy. In the era of information warfare in the electronic warfare of electronic, electronic, electronic, optical and magnetic applications, such as LSI, CCD, SAW and MSW The development of new devices has opened up new avenues for solving the three major challenges of spread spectrum communication. This article mainly expounds the application mechanism, frequency band, performance, current status and potential of three new types of functional devices in spread spectrum communication equipment. In particular, it emphasizes the design idea and production method of the spread spectrum communication device based on the novel device convolver, correlator and matched filter.
