Emitter detection and tracking algorithm for a wide band multichannel direction-finding system in the HF-band

This article describes an emitter detection and tracking algorithm which can be used to process the wide band multichannel data from a direction-finding (DF) system. The result is a list of active emitters including their basic characteristic parameters, e.g. frequency, bandwidth, azimuth and elevation. The different processing steps are given in more detail and illustrated with real data.
