We present in this paper a method to compare scene classification accuracy of C-band Synthetic aperture radar (SAR) and optical images utilizing both classical and quantum computing algorithms. This REU study uses data from the Sentinel satellite. The dataset contains (i) synthetic aperture radar images collected from the Sentinel-1 satellite and (ii) optical images for the same area as the SAR images collected from the Sentinel-2 satellite. We examine classical neural networks to classify four classes of images. We then explore Quantum Convolutional Neural Networks and deep learning techniques in terms of their training and classification performance. A hybrid Quantum-classical model that is trained on the Sentinel1-2 dataset is proposed, and its performance is then compared against the classical model in terms of classification accuracy.

This paper presents algorithms, simulations, and results on the use of optical and Synthetic Aperture Radar (SAR) quantum image fusion and machine learning algorithms for radar and remote sensing applications. We propose novel quantum image fusion techniques that extract meaningful features for identifying and classifying scenes obtained from the BigEarthNet dataset. Specifically, this work focuses on multi-label scene classification using quantum image fusion of C-band SAR and optical imagery from the BigEarthNet dataset. The proposed fusion techniques enhance and sharpen structural and textural details that are not readily observable in raw SAR imagery, thereby improving downstream classification performance. To enable quantum image fusion, we design new quantum circuits that employ unitary and Pauli gates for phase encoding of pixel intensity values. These circuits allow optical and SAR image information to be encoded and fused within a quantum processing framework. Three fusion strategies are investigated, resulting in three distinct quantum image fusion models. Comparative evaluation of these models demonstrates that pixel-averaging–based quantum fusion yields improved classification accuracy relative to alternative fusion approaches. The fused images are subsequently processed using deep classical neural networks to perform scene classification. Our neural network study begins by customizing the Visual Geometry Group 16 (VGG16) architecture for multi-label remote sensing classification tasks. In addition, we examine the use of a Residual Network 50 (ResNet-50) architecture and provide comparative performance analysis between the two models. The effects of quantum noise on the fusion and classification pipeline are also studied to assess robustness under realistic quantum processing conditions. To evaluate classification performance, we employ standard metrics such as F1 and F2 scores, and additionally introduce false discovery rate and false negative rate metrics to provide a more comprehensive assessment of classification accuracy, particularly in multi-label settings. Overall, the results demonstrate the effectiveness of optical and SAR quantum image fusion in enhancing scene classification performance and highlight the potential of integrating quantum image processing with deep learning for advanced remote sensing applications.
The field of quantum computing, especially quantum machine learning (QML), has been the subject of much research in recent years. Leveraging the quantum properties of superposition and entanglement promises exponential decrease in computation costs. With the promises of increased speed and accuracy in the quantum paradigm, many classical machine learning algorithms have been adapted to run on quantum computers, typically using a quantum-classical hybrid model. While some work has been done to compare classical and quantum classification algorithms in the Electro-Optical (EO) image domain, this paper will compare the performance of classical and quantum-hybrid classification algorithms in their applications on Synthetic Aperture Radar (SAR) data using the MSTAR dataset. We find that there is no significant difference in classification performance when training with quantum algorithms in ideal simulators as compared to their classical counterparts. However, the true performance benefits will become more apparent as the hardware matures.

Previous efforts in the classification of synthetic aperture radar (SAR) images using quantum machine learning provided encouraging results but, nevertheless modest accuracy. In this paper, we propose a novel quantum image fusion technique used for identifying and classifying objects obtained from C-band SAR and optical images. More specifically, we design a four-qubit quantum circuit to process the SAR image dataset. This method enhances the spectral details otherwise not seen when using the raw SAR dataset. In addition to the quantum circuit, we design deep neural networks (NN) to improve classification results. The Visual Geometry Group 16 (VGG16), a convolutional neural network that is sixteen layers deep, is customized and used for classification. The merit of quantum fusion as well as the promising results in improving the overall system and the potential of lowering size, weight, power, and cost (SWaP-C) is described.
