Abstract :
A detailed analysis is presented on the chaotic dynamics of moving target echoes produced by phase coded continuous wave (PCCW) radar. Based on real sampled data, the chaotic dynamics of different kinds of target are proved by three principal chaotic invariants, namely, correlation dimension, Lyapunov spectrum, and Kolmogorov entropy. The feasibility of target recognition based on these extracted features is discussed.
