Integrering av sensorer för kommunikationsunderrättelse med avancerade processystem 

Integration with Direction Finding (DF) Networks

Direction finding (DF) is essential for locating signal sources and tracking targets. HUGIN 4000 may be integrated with DF networks using methods such as: Time Difference of Arrival (TDOA), which measures the time delay between signal arrivals at different sensors to triangulate the source; and Angle of Arrival (AOA), where an array of directional antennas determines the incoming angle of a signal.

Phase coherence of inputs is key to achieving accurate angle of arrival estimation, and for this reason, HUGIN 4000 allows sharing of local oscillators across RF inputs. HUGIN 4000 may also optionally include an enhanced timing module for IRIG-B or GPS, for even more accurate timestamping of interceptions. Thus, the time of arrival may be compared between multiple spatially-distributed HUGIN 4000 sensors for performing TDOA.

Integration of spectrum monitoring with direction finding capabilities provides improved situational awareness and enables real-time location tracking of emitters for military, law enforcement and security applications.

Integration with I/Q Recording for Signal Research and Countermeasure Development

I/Q data represents the raw, unprocessed RF signal and is crucial for deep signal analysis and reprocessing. High-fidelity I/Q data capture allows analysts to examine signals in greater detail, apply machine learning algorithms for signal classification, and revisit historical signals for further investigation. This capability is invaluable for understanding complex signal structures and developing countermeasures against emerging threats. 

Feature extraction techniques help identify modulation types, signal strength variations, and bandwidth characteristics. Automated classification using artificial intelligence recognizes known and unknown signals, while threat assessment evaluates intercepted signals for intelligence significance. Correlating signals with existing databases helps detect patterns and track adversary communication techniques, allowing intelligence teams to stay ahead of emerging threats. 

HUGIN 4000 allows complex 64-bit I/Q data to be streamed for recording and post-processing, with an option for VITA 49 compliance for interoperability with common signal processing platforms. 

Integration with Voice Recording and Human Language Technology (HLT)

For intelligence operations, recording and storing voice communications intercepted by COMINT sensors is critical. The process involves extracting voice data by demodulating analogue or digital transmissions, storing and indexing recordings for future retrieval and analysis, and synchronising voice recordings with metadata such as geolocation and signal characteristics. These capabilities allow analysts to review intercepted conversations, detect patterns, and identify speakers, significantly enhancing intelligence-gathering efforts.

Human Language Technology (HLT) enhances the ability to process and analyse voice communications intercepted by RF sensors. Automatic Speech Recognition (ASR) converts voice into text, making it easier to search for keywords. Speaker identification catalogues different voices based on their unique characteristics, while language identification and translation enable real-time understanding of foreign-language communications. Additionally, keyword spotting and sentiment analysis can help to identify critical phrases, threats or emotional tones. These integrations improve the speed and accuracy of intelligence analysis.
