Abstract
Target detection under strong clutter is a relevant issue in many civilian and military application scenarios. Structured data based Deep Neural Networks (DNNs), such as Convolutional Neural Networks (CNNs), can automate feature extraction of radar time series and achieve better detection performance. We present in this work a target detection method to exploit spatial-temporal joint information of signal samples between Pulse Doppler (PD) radar range cells. The key point of proposed solution relies on the transformation of traditional signal time-series to graph-structured data, and application of Graph Attention Networks (GAT) to classify graph-structured data nodes. The presented results, achieved by processing PD radar data, demonstrate the validity of proposed method.
