Abstract

Abstract:

Accurate identification of the behavioral intentions of radar emitters is crucial in modern radar countermeasures. This paper proposes a radar behavioral intention identification method based on a multi-scale model space. By employing a sliding window mechanism, time-series segments are extracted from radar signals and subjected to multi-scale decomposition to obtain subsequences at different time scales. These subsequences are fitted using echo state network (ESN), capturing their patterns of change. Multiple ESN models are integrated to form a “multi-scale ESN model,” representing the original signal and facilitating the mapping from raw data to model space. Additionally, a metric operator in the model space is introduced to identify the optimal decision boundary, enabling precise classification and intention prediction. Experimental results demonstrate that the propsed method significantly enhances response speed and identification accuracy compared to traditional methods.

Key words: model space, radar emitter behavior intention recognition, echo state network (ESN)
