Preprocessing for Adaptive Spatial Filtering in Ground-Based Rotating Radar Systems

Beamspace post-Doppler STAP in ground-based rotating radar systems

“…However, this processing requires that jamming alone reference data are available to compute adaptive spatial filters, or that a preprocessing of training data is used. Since those reference data may not be available and the effectiveness of preprocessing degrades with clutter decorrelation and antenna rotation [10], this processing cannot be used in every scenarios. Here, we propose a space-time processing which does not require the availability of jamming alone reference.…”
