Chaotic signal reconstruction with application to noise radar system
ABSTRACT In this paper, we present a new method that is accurate and has low computational complexity to estimate the initial condition of chaotic signal. Then the estimation method is applied to a noise radar system using noncoherent reception scheme. In the new scheme, the received signal correlates with the estimated transmitted signal by the estimation method proposed in this paper. The new scheme avoids a difficult problem that how to accomplish the transmitted signal delayed by delay lines when the signal band is large. Finally, computer simulations are performed to illustrate the effectiveness of the proposed scheme.
