Abstract

Radar-based noncooperative target recognition (NCTR) can be attempted based on various types of radar signatures. One natural choice for such a signature domain is that of ultra-high range resolution (UHRR) profiles. These profiles provide a one-dimensional `map' of the target scatterers in the range dimension (with respect to the radar line of sight). Research in this area has shown that this signature domain seems to hold much promise, but that there are concomitant challenges that arise in connection with its exploitation. Radar waveform development, algorithm selection and development, data generation, and algorithm training and testing are all areas that can present acute challenges. This paper focuses on the issues related to the extreme variability that one may expect in UHRR signatures of fixed-wing targets. The degree of variability is quantified and it is shown that this extreme variability contributes to challenges related to algorithm development, training, and testing.
