Delivering a cost-effective yet robust and accurate DF
solution for government, military, and law enforcement
applications, the WiNRADiO WD-7200 direction finding
system employs a sophisticated correlative-vector matching interferometer DF method, combined with
statistical signal processing.
The system is small, lightweight and ruggedized. It is
suitable for stationary, vehicle-mounted and transportable
deployment. It delivers unparalleled flexibility due to its
SDR architecture. Excellent accuracy and sensitivity
ensure it is capable of filling not only the role of a
direction finding system, but also that of a highly capable
HF/VHF/UHF COMINT intercept receiver system.
Each WD-7200 system comprises of three main parts:
antenna radome, twin coherent receivers, and processing
The radome uses eight sense antennas in a circular array
mounted within a weatherproof fiberglass housing. The
sense antennas are specially designed dipoles. Also
inside the radome is an accurate magneto resistive digital
compass, ensuring that the antenna is referenced
correctly to magnetic north at all times.
The receivers are a quasi-coherent variant of the well-proven
WR-G39DDC SDR. The system is housed in a
rugged transportable pelicase-style enclosure.
