TCI Model 802W HF DF Subsystem Wideband HF DF COMINT Subsystem

TCI Model 802W Wideband HF COMINT Subsystem

The TCI Model 802C Subsystem integrates with TCI’s Blackbird NextGen SIGINT system and employs a flexible client-server architecture that provides a complete set of tools to carry out HF radio surveillance.

The system rapidly acquires and describes any traditional or modern HF signal activity, and subsequently performs detailed analysis of specific Signals of Interest (SOI). The 802W can carry out this analysis manually or automatically in real time or in delayed (post-facto) mode. The analysis includes detection, location, collection, classification and archiving of signal activities.

Under typical conditions the 802W system rapidly searches the HF spectrum using extremely fine resolution. When RF energy is detected, the system automatically determines the direction of the energy source and all other important signal parameters. This information is then automatically archived for future analysis and can be simultaneously passed in real time to operator client workstations. The operator at a client workstation tasks the system to find a particular signal of interest with specific parameters. The system then processes archived or real-time data to find the SOI and its geographic position or location and presents this information to the operator.

The foundation of the 802W system is high-speed signal search, combined with detection and direction finding obtained by simultaneous, parallel processing of multiple, 28 MHz-wide channels connected to an antenna array. The 802W is capable of performing automatic real-time DF analysis on any type of HF signal. The DF analysis provides transmitter parameters including frequency, direction and/or location, bandwidth, and time of transmission.
