As an important part of electronic intelligence (ELINT) and electronic support measure (ESM) system, radar signal sorting affects the performance of electronic reconnaissance equipments directly, and is a key technology to campaign decision-making. However, as the radar systems are becoming more and more complicated, as the countermeasure activities in modern electronic warfare are becoming more and more drastic, and as the development of low-probability of intercept (LPI), the regularities of signal sorting are heavily destroyed. This leads to the results of radar signal sorting based on common five parameters are not well. At present, the deinterleaving of advanced radar signals has become the primary bottleneck of signal processing in ELINT and ESM system, and confined farther improvement of the performance of electronic countermeasure equipment. So this paper analyzes and studies the background and significance of radar signal sorting in complex systems.
As one of the key technologies for signal processing of electronic reconnaissance equipment, the research on the theory and technology realization of radiation source signal sorting has been highly valued by various countries. Relevant research literature indicates that domestic and foreign research scholars have carried out signal sorting technology for radiation source signals. A lot of research work has also achieved a lot of results. In foreign countries, a large number of papers on signal sorting have been published in many important international journals and conferences. Each paper has achieved certain innovations and improvements in technology, which has greatly promoted the development of signal sorting. In China, many research institutions and institutions of higher learning have strengthened the research on the identification and sorting of radar signals from complex systems, and explored a theoretical system that can effectively support the technical improvement of radar emitter signal identification and sorting.
