Abstract : The use of passive sensing for derivation of HF system control data has advantages over active techniques from both tactical and spectrum conservation points of view. In this paper methods are described by which ionospheric data may be from passive sensing of the HF spectrum. Data derived using these techniques may be used in the operational decision process to control automated hf communication systems. The techniques described are facilitated by the availability of powerful, low-cost signal processors and fast tuning receivers allowing a high level of signal processing to be performed in real time.
