System Description

The TC-9300 Tactical DF System provides advanced geo-location capability over the 30 to 3000 MHz range with an option for 3000MHz to 6000MHz coverage, and signal intercept over the 20-6000 MHz range in a next-gen single channel architecture. From 1 to 3 COMINT signal intercept and analysis channels can be added for simultaneous DF and COMINT functions. The system is designed for tactical ground, vehicle, shipboard, airborne and leave-behind applications. Systems are complete with a choice of DF array to fit the application, DF receiver channel (SDR tuner-digitizer), DF processor/demodulator, choice of rugged PC, tablet or Droid and battery pack/AC-DC power adapter. Windows based software and GUI is provided for system control, BIT status, RF/Baseband spectral displays, DF LOB plots, moving map display and mission data logging. The receiver channel and DF processor is mounted at the antenna location eliminating the requirement for long RF coax cable runs. The system includes a built-in GPS and electronic compass and accepts external platform NAV data. The TC-9300 provides direction finding and signal intercept for AM, NBFM, WBFM, USB, LSB, CW and PM signals. Optional Krypto500/1000 and Signal Works/Mod-Rec decoding, classification and analysis software packages are available to address a wide range of complex signal formats.
