On some simple estimates of ATR performance, and initial comparisons for a small data set

摘要

In this paper, we present an initial development of simple approximations for the the perfor¬mance of, real-aperture radar ATR systems. In particular, we develop estimates of target separa¬bility using channel-capacity-like approximations, based on sensor constraints, and combinatoric-driven approximations, based on constraints imposed by the target. We then use these approxi¬mations to form estimates of the classification error probability for the ATR system. Finally, these estimates are compared with classification results for a small data set containing both synthetic and measured down-range responses from aircraft objects.
