Abstract
Transceivers are critical components of phased array radar (PAR) systems, and accurate fault diagnosis is essential for ensuring their reliability. However, many transceiver faults exhibit similar characteristics, making them difficult to identify. To address this challenge, a two-stage fault diagnosis method employing both rough and fine classifiers is proposed for PAR transceivers. In the first stage, a weighted support vector machine serves as the rough classifier to effectively separate easily distinguishable faults. For more complex faults that remain ambiguous, Fisher’s discriminating ratio is used to identify the most significant monitoring variables, refining the analysis further. In the second stage, a sparse momentum deep belief network (DBN) is developed as the fine classifier to accurately identify these challenging faults. The configuration parameters for both classifiers are optimized using a modified equilibrium optimizer to maximize performance. The proposed method is validated using a real-world dataset of PAR transceivers, with test results demonstrating superior accuracy compared to several existing intelligent diagnostic methods.
收发器是相控阵雷达(PAR)系统的关键部件,准确的故障诊断对确保其可靠性至关重要。然而,许多收发器故障具有相似的特征,因此难以识别。为了应对这一挑战,我们提出了一种针对 PAR 收发器的两阶段故障诊断方法,同时采用粗分类器和精分类器。在第一阶段,加权支持向量机作为粗略分类器,可有效区分易于区分的故障。对于仍不明确的较复杂故障,则使用费雪判别率来识别最重要的监测变量,进一步细化分析。在第二阶段,开发了稀疏动量深度信念网络(DBN)作为精细分类器,以准确识别这些具有挑战性的故障。两个分类器的配置参数都使用改进的平衡优化器进行优化,以最大限度地提高性能。使用 PAR 收发器的真实数据集对所提出的方法进行了验证,测试结果表明,与现有的几种智能诊断方法相比,该方法具有更高的准确性。
