摘要：本文提出了一种基于卷积神经网络（CNN）和接收信号强度（RSS）的分类方法，以解决态势感知中的非合作辐射源波束状态感知问题。以RSS、传感器坐标和接收信号频率作为CNN的输入特征，真实波束状态作为CNN的输出。为了增加特征向量中包含的RSS梯度变化，提出了一种多层观测阵列来测量RSS。仿真结果表明，该方法对接收阵列位置扰动具有鲁棒性，对目标位置失配和主瓣第一零点宽度失配具有泛化能力。

Abstract:In this paper, a classification method based on convolutional neural network (CNN) and received signal strength (RSS) is proposed to solve the problem of non-cooperative emitter beam state sensing in electrical situational awareness. RSS, sensor coordinates, and received signal frequency are taken as the input features of CNN, while real state is taken as the output of CNN. To increase the RSS gradient contained in the eigenvector, a multi-layer sensor array is proposed to measure RSS. Simulation results show that the proposed method is robust to array location disturbance, and has the ability to generalize the mismatches in target location and main lobe beam width between first nulls.
