ATR performance assessment of target type number for HRR radar

Automatic target recognition (ATR) performance evaluation has become an important subject in ATR theory community since the last two decades. The extended operation condition (EOC) and system cost are two key aspects in ATR performance evaluation. For the situation of air-to-ground (A-G) ATR using high range resolution (HRR) data, this paper analyzes the influence of target type number on ATR system performance. The system cost is also considered in evaluation process. An experiential performance model of typical ATR systems is given. The performance model and the corresponding conclusions have useful reference to ATR system performance prediction and assessment in the similar A-G applications.
