PROJECT TITLE :
Interference Investigations of Active Communications and Passive Earth Exploration Services in the THz Frequency Range
ABSTRACT:
At Terahertz (THz) frequencies, passive space-borne Earth exploration services could be interfered by upcoming active communication applications. Aiming for coexistent use of the THz band by both active and passive applications, this paper identifies essential eventualities where interference will probably occur. Atmospheric attenuation simulations are used together with acceptable propagation models to account for proper state of affairs-specific wave propagation conditions. Furthermore, distance-dependent measurements of the trail loss are taken at three hundred GHz. The atmospheric attenuation and propagation models are then utilized so as to simulate potential interference powers for the individual reference situations underneath worst case-conditions. Based on existing information for the maximum allowed interference, tips for applicable system specifications of active THz hardware (e.g., transmit power constraints) are developed and achievable system performances are evaluated. Countermeasures against potential interference are mentioned. Therefore, any interference will be anticipated and compensated for already in the early design part of THz communication systems.
