Abstract
This paper studies genuine and dummy ballistic warheads identification using multiple-input and multiple-output (MIMO) radar. State space model (SSM) is used to describe the kinetic characteristics of the warheads. Identification of the genuine and dummy warheads is accomplished by solving a binary hypothesis testing problem. Sequential detection method is employed. Since sophisticated dummy warhead are made very similar to the genuine one, it is very difficult for conventional sequential detectors to tell them from the genuine ones. We consider to employ locally optimal unknown direction (LOUD) test, which has been proved to have the advantage of distinguishing small differences. Sequential LOUD (SLOUD) test is proposed. It is shown that the performance of the SLOUD test based identification method is superior than the sequential detection method based on the conventional mismatched likelihood ratio (LR) test or the generalized LR (GLR) test.

Assume the SSM system parameters are known for the genuine warheads based on some preprocessing or the available data base.
