Detection of weak target signals based on chaotic characteristics of sea clutters
Xu Wei · Radar & Ecm · 2007
The correlation dimension and largest Lyapunov exponent of sea clutters are studied in this paper.Results show that sea clutters have chaotic character.Based on the theory of phase space reconstruction of the complicated nonlinear system and the feature of chaos that can be forecasted in short term,a method of detecting weak signals in sea clutters through neural networks is presented,and the detecting model of radar is introduced.
