The method includes capturing, at one or more antennas, radio frequency (RF) emissions preceding a broadband emission event. The RF emissions are then recorded at one or more broadband receivers over a period of time. A first tuning of the received RF emissions is selected to detect ionospheric reflections, and a second tuning of the received RF emissions is selected to detect direct line of sight emissions. From the selected tunings, an amplitude or complex time series of the second tuning with one or more channels of the first tuning are correlated to calculate a relative virtual echo height of the ionosphere."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Receive only ionosonde using broadband emissions as signals of opportunity","description":"A system, computer program product and method of examining the ionosphere is disclosed.
