摘要

本文提出了一种利用人工神经网络定位目标的微波成像新方法。经过训练的神经网络从测量的散射数据重建断层图像，例如非线性电磁逆散射求解器。通过网络预测和目标值之间的交叉熵来确定隐藏神经元的适当数量。为了通过实验验证这种方法，我们建立了一个由16个天线组成的试验台，这些天线在水下发射和接收950 MHz的微波，并使用直径为2毫米的金属棒作为定位目标。结果显示出优异的成像性能，具有较少的伪影和小于2mm的定位误差。

A Neural Network-Based Microwave Imaging Method for Object Localization

This paper presents a new microwave imaging method using artificial neural networks to localize an object. The trained neural network reconstructs a tomographic image from the measured scattering data, such as a nonlinear electromagnetic inverse scattering solver. The appropriate number of hidden neurons is determined through the cross-entropy between network predictions and target values. To verify this method experimentally, we set up a testbed consisting of 16 antennas that transmit and receive 950 MHz microwaves underwater and used a metal rod with a diameter of 2 mm as a localizing target. The results show excellent imaging performance with fewer artifacts and less than a 2-mm localization error.
