Extension of Digital Modular Radio to Hf Domain
نویسندگان
چکیده
General Dynamics C4 Systems extends the Digital Modular Radio (DMR) system to the High Frequency (HF) domain. Base-band serial and parallel tone modem functionality is integrated with embedded, AIM-based KY-99A, KWR-46, and KG-84C cryptographic algorithms plus single-sideband (SSB) radio frequency (RF) modulation to provide four channels of HF plain text (PT) and cipher text (CT) communication. An Automatic Link Establishment (ALE) controller is added, to provide call management and link quality monitoring capabilities for both HF line-of-sight (LOS) and sky wave channels, in the first software defined radio (SDR) system funded by the United States Navy.

متن کاملA Software-defined Radio Ionospheric Chirpsounder for Hf Propagation Analysis
Advanced users of high frequency (HF) radio communications have long used systems known as chirpsounders 1 to obtain real-time information about the ionospheric propagation conditions of different communication channels between a transmitter and a receiver. Traditional chirpsounders are expensive to realize and lack the flexibility of state-of-the art digital radio platforms. However, the adven...
متن کاملExperimental Analysis on Spatial Dynamics in Wide-Aperture 2-D HF Radars
Digital data collected from each element of a L-shaped wide-aperture HF radar aperture can be examined offline with various beamforming and direction finding algorithms to assess statistical characteristics of received signals. This paper examines data on radio sources propagating to the HF radar via refraction off the ionosphere. The variations of the spatial properties of radio sources are ex...
