Spatio-temporal processing with ground-based rotating radar systems

Abstract

This paper considers spatio-temporal filtering in ground-based rotating radar systems. After the drawbacks of the standard spatio-temporal processing in this context are underlined, an hybrid spatio-temporal scheme is proposed to overcome them. Finally, this introduced processing is compared to standard ones through Monte Carlo simulations.

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

“…This question has already been investigated in [9] where the use of a separable spatial then temporal STAP processing has been proposed. 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.…”

“…First, let note that after beamforming with rotation compensation, Doppler spread of clutter echoes is limited, as analyzed in [9]. Therefore, apart from powerful echoes seen in the antenna sidelobes, clutter can be efficently mitigated by standard non adaptive Doppler filtering, corresponding to the case Q = 1.…”
