Detection Technology of Pulse Signal Based on Ambiguity Function
Da Huo · Radio Engineering · 2012
In modern battlefield,more and more complicated and varied electronic systems and operating modes are emerging,and the wide application of advanced systems makes modern electronic countermeasure(ECM) face much denser and complex electromagnetic environment.Therefore,detection technology of pulse signals becomes one of the key technologies that should be addressed urgently in ECM.In terms of electronic reconnaissance,pulse component separation and each component of the ambiguity function are discussed based on time-frequency analysis theory,electromagnetic signal reconnaissance is analyzed and discussed with its essential feature,simulation and evaluation are performed,and the result shows the advantage of the technology.
