RADIO-MONITORING INSTRUMENTATION COMPLEX 'ROSOMAKHA' FOR LF, IF, AND HF BANDS

摘要

FIELD: radio engineering.;SUBSTANCE: proposed radio monitoring instrumentation complex is designed for monitoring frequency band ranging between 0.03 and 30 MHz is built of spatially dispersed fixed radio monitoring stations remotely serviced through communication channels of central supervision control point; each fixed radio-monitoring station has antenna assembly built of four independent phased longitudinal/transverse-slot antenna arrays installed on antenna platform; each independent antenna array is assembled of twelve annular loop antennas installed in four-antenna groups to form three strips, phasing devices, phasing unit, and amplifying unit; the latter are connected to power amplifier and then to antenna polyplexer division post; it also has instrumentation device assembled of set of detecting, direction finding, and technical control pieces of equipment.;EFFECT: ability of on-line monitoring and high-precision measurement of electromagnetic environment on large areas.;3 cl, 3 dwg
