ou may have noticed that this month's JED cover is a bit
different - perhaps even a bit "psychedelic." What you're
looking at on the cover is a representation of the earth's
ionosphere, home of the colorful nighttime auroras above
the north and south poles. Aside from its spectacular lightshow, the ionosphere plays a critical role in High Frequency
(HF) radio propagation, as amateur (ham) radio operators know very well.
This month, JED is taking a look at the HF region with a couple of articles. In his piece, "Back to the Future with HF SIGINT," John Haystead
writes about the HF challenges facing the SIGINT community. With a
growing number of HF radio users, more sophisticated HF radios becoming available, and a somewhat distracted intelligence community, HF SIGINT is at risk of falling behind the curve.
The second article, HF SIGINT Battles the Ionosphere," by Barry Manz,
focuses on what makes HF SIGINT so different (and so difficult) compared with other frequency ranges. These challenges include multipathinduced signal fading, a noisy environment due to increasing use of HF
radio and radar, and ionospheric variations, to name few.
To be fair, the intelligence community is taking steps to address
its growing HF SIGINT challenge. The Intelligence Advanced Research
Projects Agency (IARPA) has been working on the problem via its High
Frequency Geolocation (HFGeo) and Signal Location in Complex Environments (SLiCE) programs. IARPA wants to leverage a variety of advances in
areas such as high-dynamic-range receivers, adaptive signal processing,
antenna technology and ionospheric ray path prediction. On August 21,
IARPA will hold an HFGeo Proposer's Day meeting to brief industry about
the next phases of the program.
The problem today is the gap that is opening up between the number
of HF users (and the sophisticated technology to which they have access)
and our ability to monitor dangerous groups that communicate via HF.
Because of this gap, there is legitimate concern that entities with global
and regional operations, like Al Qaeda, can covertly communicate with
greater ease.
Government organizations and industry are innovating through programs, such as HFGeo. However, greater effort and awareness are needed
if governments want to close the HF SIGINT gap. - J. Knowles
