| Abstract: | The in pulse characteristic extracting technology of signal is an important research content in electronic warfare, which is crucial for the deinterleaving and recognition of signal in high density and complex environment. Extracting the in pulse characters based on direct sampling from IF signal and quadrature coherent detection is proposed. Simulations are performed and show that the proposed technology and its results prove its efficiency. |
