Software Radio Applied in Electronic Countermeasure System

Electronic countermeasure system is an electronic weapon system with sophisticated electronic reconnaissance, electronic attack and electronic defence capability. It is necessary to investigate and develop an integrated electronic countermeasure equipment with wide frequency bandwidth, adaptability and expansibility. The technology of Software Radio provides an optimum method to solve this problem. First the basic and key concept of Software Radio are introduced in this paper. Then on the basis of Software Radio the principle of electronic countermeasure reconnaissance receiver and jammer are discussed in detail. Finally the points which should be considered in practice are also provided.
