Space-time adaptive processing (STAP) is a well-known and effective method to detect targets, obscured by interference, from airborne radars that works coherently combining signals phased antenna array (spatial domain) with multiple radar pulses (temporal domain). As widely demonstrated, optimum STAP, in the sense of maximizing output signal interference plus noise ratio (SINR), coherent, linea...

We derive entropic inseparability criteria for the phase space representation of quantum states. In contrast to involving differential entropies marginal distributions, our are based on a joint distribution known as Husimi Q-distribution. This is experimentally accessible in cold atoms, circuit QED architectures and photonic systems bears practical advantages compared detection marginals. exemp...
