Intra-pulse Intentional Modulation Recognition of Radar Signals at Low SNR

Intra-pulse features extraction of radar is of great research significance in electronic reconnaissance technology. With continuous development and equipment of the new system radar, the characteristics of the modern electromagnetic environment could be summarized as density, complexity and variability, which make the traditional signal identification methods difficult to achieve the desired effect. Therefore, this paper is devoted to the study the methods and performance analysis in extracting intra-pulse features of radar emitters in complex electromagnetic environment, especially in low SNR environment. The final recognition effect exceeded 0db SNR.
