Abstract

This paper presents a velocity estimation method to addresses the steering vector mismatch of angle measurement and adaptive coherence estimation (ACE) in mDT space-time adaptive processing (STAP). The proposed velocity estimation method is dual to the adaptive monopulse in space-domain, and it can be conducted in a simple process framework. Numeric results show that the angle estimation errors are well reduced and detection aided with ACE are improved.
