Research On Algorithms For Radar Emitter Signal Sorting In Complex Environments

With the development of the radar technology, radar has been more diversiform and complicated. The electromagnetic environment that ECM (Electronic Counter Measure) is faced with has been more and more complex. How to sort and analyze signal accurately is an important research of ECM.The paper analyzes the characters of signal environment and discusses the parameters for signal sorting. The paper discusses several sorting algorithms and presents a multi-parameters signal sorting algorithm and specifies every process of the algorithm. At the pre-sorting stage, the paper analyzes accuracies of the sorting parameters and improves the c-means clustering algorithm to realize the pre-sorting. During the PRI sorting, the paper introduces several sorting algorithms firstly, and then analyzes their advantages and disadvantages. Finally, the paper improves the CDIF algorithm to reduce the computation and improve the algorithm efficiency.The simulation shows that the method can realize the accurate sorting and recognition.
