iming at the problem that there are some defects and shortcomings of traditional radar emitter signal sorting model structure, the structure of radar signal sorting model based on intra-pulse characteristic parameters is analyzed. Although the model is more complete than the early recognition model, there are still some shortcomings in the face of the increasingly complex electromagnetic environment and the emergence of complex radar signal sources. This article has studied this.

Introduction

The purpose of radar emitter signal sorting is to separate the randomly interleaved signal streams using the inter-pulse and intra-pulse parameters of the signal, and use these parameters to perform the following functions [1]: (1) identify the enemy in the operational environment; (2) determine its deployment location and direction; (3) provide early warning to friendly forces based on its threats; (4) provide reconnaissance personnel with information on enemy radar technical parameters, radar systems and tactical operational characteristics. With the rapid development of modern military industry and electronic technology, the wide application of various electronic information devices has made the electromagnetic environment of electronic warfare increasingly complex. The generated electromagnetic signals are densely interleaved and the working parameters are seriously overlapped, resulting in degradation of signal sorting and recognition performance.
