| Abstract: | Extracting of radar in-pulse characteristics is an important technology to sort and recognize intercept signal from the radar countermeasure systems.The in-pulse frequency-coded signal is denoised based on wavelet analysis firstly,and then the wavelet-ridge is used to extract the in-pulse characteristics. Computer simulation proves that the effective algorithm has a referenced value. |
| Keywords: | signal noise rate in-pulse characteristics wavelet denoising wavelet-ridge |
