Non-cooperative target recognition in the frequency domain

Non-cooperative target recognition is investigated in the frequency domain using measured in-flight aircraft data. It is found that the frequency domain target signatures are distinct for different aircraft types and at different aspects. As a result, target identification in the frequency domain is just as viable as using conventional high-range resolution profiles in the range domain. In addition, there are many advantages of working in the frequency domain; many of the problems encountered in the range domain can be avoided. This leads to a much simpler task in performing target recognition.
