Abstract
This Tactical Communications workshop will cover the general area of military tactical communications, including voice and data. The electromagnetic spectrum will be discussed, and the communications bands will be defined. Various propagation modes will be considered including radio frequency line-of-sight, troposcatter, satcom, and ionospheric skywave, as well as optical. We will also consider anti-jam techniques such as frequency hopping and direct sequence spread spectrum as well as adaptive nulling of the antenna. The software defined radio and cognitive radio approaches will be discussed. In addition various modulation and multiplexing schemes will be described. The treatment will also include data links for ISR platforms. Specific systems employed by the US and NATO forces will be discussed such as Joint Tactical Information Distribution System (JTIDS), Link 11, Link 16, Link 22, Warfighter Information Network-Tactical (WIN-T), Common Data Link (CDL), Tactical Common Data Link (TCDL), Cooperative Engagement Capability (CEC), Advanced Extremely High Frequency (AEHF) system. The principles of network centric warfare will be considered.
