Structure and radiation of broadband ionosphere research station (HAARP)

The paper presents structure, main characteristics and radiation modeling of broadband ionosphere station stands for High Frequency Active Auroral Research Program (HAARP). The fundamental goal of this investigation is to explore and understand natural phenomena occurring in the Earth´s ionosphere and near-space environment. Information derived from this research will have major value in the design of future communication and navigation systems. Structure of the antenna array, transmitter units and radiation computer modeling of the station are described in the paper.
