Abstract :
An alternative skywave line-of-sight (SkyLOS) high frequency radar architecture has been proposed for early detection and tracking of ballistic missiles. It consists of a skywave over-the-horizon (OTH) radar augmented by one or more ground-based systems for line-of-sight reception in the illuminated region. The line-of-sight systems provide additional Doppler-time profiles of the target with different observation geometry to improve flight trajectory estimation. Targets compete for detection against powerful clutter and interference from manmade and natural sources. We introduce a practical STAP technique to deal with operational signal environments and demonstrate its performance on live SkyLOS data
