A SIGNAL MODEL BASED ON COMBINATION CHAOTIC MAP FOR NOISE RADAR

By Q. Yang, Y. Zhang, and X. Gu

Full Article PDF (379 KB)

Abstract:
We propose a combination chaotic map (CCM) signal model to resolve the limited-word-length problem in digitally realizing chaotic signals used for noise radar. The proposed CCM has approximated infinite dimension, much more complicated phase space structure as well as better chaotic properties. The radar signal based on CCM presents much lower PSLR of auto-correlation as well as much flatter power spectrum, so it is very suitable for generating wide-band radar signal. Simulation experiments are conducted to show the good performance of the signal.
