Abstract :
In this paper, a new closed-form expression for a common STAP performance metric (i.e., SINR Loss) is derived in terms of system parameters of interest. It is shown that this new relationship can be manipulated into new expressions for STAP Minimum Detectable Velocity (MDV) and STAP “aperture-limited” performance. These new developments are significant as they provide the first derivations that unify these concepts. As they are implemented in compact closed-form expressions, the new results are attractive for system design.
