Space-time adaptive detection for airborne multifunction radar

In this paper we combine advanced STAP algorithms and concepts for adaptive guard channels with subarrayed planar arrays together with the theoretical results available in the field of adaptive detection (GLRT, AMF, ACE tests). The aim is to define a robust adaptive sidelobe blanking detector against combined impulse and CW interference as well as strong clutter discretes. For the selection of the thresholds, we utilize the detection margin introduced as a direction dependent tool, instead of the commonly used main and guard channel antenna patterns. Numerical results are then given for a generic airborne multifunction radar system.
