Parameter Extraction Based on Second Order Statistics for PN Coded Fuze Signal

The working principle, signal form and main characteristic parameters of PN coded fuze are analyzed. The second order statistics including autocorrelation and power spectrum of PN coded fuze is studied. The power spectrum estimation methods are discussed. The arithmetic of characteristic parameters extraction based on second order statistics is presented. It is found by simulation that the feature parameters of fuze signal can be extracted effectively by the above method.
