System description

features

AFAS combines the advantages of fast search reception with detailed pc-based signal-analysis in an automatic multichannel radio-monitoring system for the HF- and VHF/UHF frequency bands.
Due to four fully equipped reception channels, four frequency sprectra can be analyzed and –if required- recorded fully automatically.

“unlimited bandwidth caused by fast seeker head”

By using one or multiple reception channels for search of radio-emissions in the corresponding frequency band, detection and subsequent fully automatic classification of signals, which are outside of limited bandwidth o other radio-monitoring systems, is enabled. A random amount of fast search-receivers for detection of radio-emissions guarantees a profound radio-reconnaissance, especially when situation of local area is unknown. As a special advantage of this system can be distinguished, that radio emissions over the whole frequency range can be detected.

“automatic and multichannel signal-search and –classification
including automatic speech identification”

The radio-monitoring system AFAS is especially designed for fully automatic signal-search and –monitoring as well as signal-analysis –on four reception channels simultaneously!-. If necessary for the mission, the system can be operated fully autarchic, without operator.
If a signal is detected, it will be processed to a free reception channel for classification and –if desired- it will be processed to recording. Recording time can be defined as fixed recording –length or as far as the end of the classified signal / emission. Speech is identified fully automatic.
Simultaneously the system supplies the type of transfer method (e.g. Stanag). Additionally each signal is provided with a time-stamp and GPS-Position.

"an user-friendly GUI with clear statistic function gives the system a very high operational benefit."

System architecture

AFAS is equipped with four identical reception channels, which are controlled by Phoenix Signal-Classification Software. The reception channels consist of a BO-35 wideband receiver (including A/D-Converter), which distinguish itself by its excellent IP3 value of +20dBm (below 1GHz).

While 1 reception channel is always seeking for radio-emissions, the remaining channels are classifying detected emissions. If detected signal is classified as speech, the signal will be recorded automatically.

Furthermore AFAS is driven by a powerful QuadCore processor, on which the signal-classification software Phoenix, database and receiver-control is running.

highest operationality by compact design
The operational concept of the fully automatic radio-monitoring system is topped off with its compact size. While other, comparable efficient monitoring systems, are designed as stationary systems, AFAS is designed for highest mobility and operational capacility.
