Abstract

Along with the development of nonlinear science, the chaotic dynamics of radar scattering are being paid more attention. The data of ground-based and airborne radar are analyzed with the chaos theory. The correlation dimension and Lyapunov exponent are calculated from space reconstruction, the chaotic characteristics for many types of scattering are revealed. It shows that radar scattering is produced by nonlinear chaotic systems with four to seven freedoms and the invariant of chaos are concerned with sea wave, terrain and relative movement between the airborne radar and the terrain or sea.
