MM-Wave Propagation and Application in Military Communications Systems,

Abstract : Tactical Communication is becoming more and more important in modern armies. After an improvement phase of Weapon- and Surveillance-Systems, emphasis is now on Command and Control and the optimization of the weapon efficiency. Hereby, communication is a dominant subsystem. According to the electronic threat new requirements, i.e. Jam-resistance, security against Interception and Deception must be fulfilled; under conditions of a high degree of mobility. Tactical communication in modern armies uses the VHF range from 30 MHz to 88 MHz. Advanced realizations, as they are operational or in introduction (Germany Army) now include digital transmission, voice and data capability and ECM-resistance by Frequency-Hopping methods and encryption. But the utilization of the VHF-band, including the traditional analog Fixed Frequency Communication (Interoperability) is strongly limited and not sufficient to meeting the Military Radio Net requirements. This is the reason for looking for new additional frequency ranges.
