Aiming at the defects and shortcomings of the traditional radar emitter signal sorting model structure, this paper proposes a new sorting model structure for the unknown source signal in complex dense electromagnetic environment, comprehensively utilizing the inter-pulse parameters and intra-pulse of the signal. Modulation features are sorted. The paper studies the problem of radar emitter signal sorting with a new idea. The characteristics and innovation of the new sorting model structure are expounded, and the functions and functions of each component of the model structure are briefly described.

Introduction

Radar emitter signal sorting refers to the process of separating randomly interleaved signal streams using inter-pulse and intra-pulse parameters of the signal. The traditional radar emitter signal sorting model structure mainly uses the five basic parameters of TOA, RF, PA, PW and DOA for sorting [1~6]. When the signal density in the electromagnetic environment is not very large, the sorting model is more effective when the conventional parameters are relatively stable. That is, the sorting method is only suitable for the sorting when the conventional radar signal parameters are basically unchanged under certain conditions. In the modern electromagnetic environment, the waveform design of radar is becoming more and more complicated. Traditional radar signals such as fixed-frequency, jagged, and jitter are becoming less and less common in modern radar design, and complex radar has become the current radar design.
