Abstract
Previously, authors investigated a technique to generate the nonlinear chaos based FM (CBFM) waveforms to achieve wide bandwidth and frequency agility. The technique relied on the output of the Lorenz chaotic circuit. In this paper, authors present the potentials of Rossler based chaotic FM waveforms for wideband radar imaging and assess its statistical properties such as ergodicity, stationarity and invariant probability density functions. The correlation properties and ambiguity functions are illustrated to assess its resolution and electronic counter-counter measure capabilities (ECCM). Using the theoretical and experimental studies, a comparison will be performed between the CBFM waveforms generated using the Lorenz chaotic oscillator and the Rossler chaotic oscillator. Finally, a generalized approach on the utilization of chaotic systems for high range resolution and bistatic radar applications will be presented.
