Comparison of DTSO and DERA HF Background Noise Measuring Systems with the International Radio Consultative Committee (CCIR) Model Data

摘要

A comparison of two High Frequency background noise measuring systems (BNMS) that employ different hardware and signal processing techniques has been conducted. One system was part of the Frequency Management System at the Jindalee over-the-horizon radar Facility at Alice Springs (JFAS) and the other system was based on a design supplied by the UK's Defence Evaluation Research Agency. The UK BNMS was placed at JFAS so that both systems could independently analyse the same external noise environment. The measurements from both BNMS were compared with the International Radio Consultative Committee (CCIR) HF atmospheric background noise model.
