WD-7200 HF/VHF/UHF Interferometer-based Correlative DF System
>>> Prices and availability on request!
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 computer.
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.
The WD-7200 exploits a special technique of phase equalization that is both passive and dynamic, ensuring instantaneous optimum performance at all times.
The WD-7200 DF technique allows DF and exploitation of many of the new digital waveforms, not possible with pseudo doppler and other analog systems. These include DMR/MOTOTRBO, dPMR, NXDN, D-STAR and APCO P25 (phase 1 and phase 2).
Combining modular hardware design with innovative software, the WiNRADiO WD-7200 HF/VHF/UHF direction finding system delivers unprecedented flexibility and performance.
