We use firmly defined processes which we have developed for the DARC's Intruder-Watch (Intruder Monitoring Department) on the basis of our experience in business and the military and which we have further developed for our interest group.
1
Reception
We receive reports from radio amateurs and SWLs or receive non-amateur radio emissions ourselves with our measuring and receiving stations.
2
Signal classification
In a next step, we determine the method of the signal. This process is called classification.
3
Analysing parameters
We then measure the exact parameters of the signal. For example, the shift, phase position, bandwidth, channel spacing or the PRF/SPS for over-the-horizon radars (OTHR).
4
Radio direction finding
We operate software that allows us to carry out radio localisation in the 1-30 MHz range. As a rule, we carry out this type of localisation several times for new signals.
5
Profiling
Our sophisticated profiling system helps us to recognise emissions and their patterns of occurrence at an early stage. This allows us to create a profile of the intruder.
6
Translation (Phonie)
In the case of foreign-language phonetic transmissions whose content we do not understand, we can rely on an extensive network of translators who can make the content accessible to us.
7
Notification authority/station
Once we have summarised all the information, we can contact the interfering station directly or submit a report to the Federal Network Agency.
8
Feedback to submitter
If it is a report from a radio amateur or SWL, the person submitting the report will receive well-founded and structured feedback from us. Incidentally, this also applies to every relevant intermediate step.
