| Abstract: | The research status of ballistic missile target motion feature extraction and radar recognition is introduced.Then,a typical motion model is set up for a cone-shaped ballistic missile warhead target with uniform precessing rate,steady precessing angle and stationary cone tip.An analytic expression of the echo from the target is proposed.Fourier transform and time-frequency transform are used to analyze the echo signal by means of numeric method.Based on above mentioned analysis,spectrum and micro-RCS of ech... |
