Interference from HF Radar
Abstract
Interference to communication reception near an HF radar is dependent on many factors. It is shown that the most important of these that can be controlled is the pulse shape of the radar. Under optimum conditions, acceptable reception should be possible with frequency separation as little as 21 kHz from the proposed radar. At separations up to 450 kHz, only occasional interference problems are expected. Measurements with the NRL HF research radar indicate that the radar is undetectable beyond 200 kHz from the radar frequency. The radar peak power was 1.83 MW, a 270-microsec pulse essentially cosine squared was employed, and the receiver was at a distance of 16.22 km across the Chesapeake Bay.
