Abstract

Shortwave communication plays a critical role in military and emergency applications. However, the complex nature of shortwave transmission channels makes automatic burst signal recognition particularly challenging, especially in non-cooperative scenarios. This letter presents an optimized recognition method based on the You Only Look Once (YOLO) network, which accurately identifies signal types while improving the precision of burst time detection. A Physical Intersection over Union (PIoU) is proposed by leveraging the bounding box’s left edge, corresponding to signal burst time, to refine bounding box regression and resolve ambiguities in conventional IoUs. Experiments show the proposed PIoU improves the accuracy of burst time detection by 10.44% under Signal-to-Noise Ratios (SNRs) from -20dB to 18dB, compared to the state-of-the-art IoU methods. Further tests across 8 shortwave communication channels confirm consistent improvements of burst time detection, while other metrics such as Precision, Recall, mean Average Precision at 50% IoU(mAP50), and mAP95 are maintained. These advancements significantly benefit signal decoding and information restoration.

基于物理io的YOLO网络短波通信突发信号识别

短波通信在军事和应急应用中发挥着关键作用。然而，短波传输信道的复杂性使得自动突发信号识别特别具有挑战性，特别是在非合作场景下。本文提出了一种基于YOLO （You Only Look Once）网络的优化识别方法，在准确识别信号类型的同时提高了突发时间检测的精度。通过利用边界盒的左边缘（对应于信号突发时间），提出了一种物理交集（PIoU），以改进边界盒回归并消除传统边界盒中的歧义。实验表明，在信噪比（SNRs）为-20dB ~ 18dB的情况下，与现有的IoU方法相比，PIoU方法的突发时间检测精度提高了10.44%。在8个短波通信信道上的进一步测试证实了突发时间检测的持续改进，而其他指标，如精度、召回率、平均平均精度在50% IoU（mAP50）和mAP95保持不变。这些进步对信号解码和信息恢复具有重要意义。
