| Abstract(in English) | We have proposed a UWB chaos radar, whose transmitted signal is generated by a chaotic map. Chaos is nonperiodic and could generate a sequence with infinite length theoretically. Although the sequence looks like a noise, the value can be predicted exactly if the dynamics and the initial value are provided. If the feature of chaos is exploited, a radar with outstanding performance can be expected. It is important to remove various noises called clutter in a radar. In this study, we focus mainly on removal of clutters by employing two noise reduction methods. We use the Minimum Distance Approximation method and Maximum-Likelihood Decodings method to remove the clutter. When we carried out computer simulations as changing signal-to-noise ratio (S/N), probability density distributions show recovered signals and we can evaluate clutter reductions. |
