Abstract

Remote sensing is an advanced technology to explore the space and acquire earth-space information, with its accurate, comprehensive and dynamic detection and observation ability, RS plays an key role in earth observation, national defense, aerospace and deep space exploration. The advancement of science and urgent demands in economy and other fields put forward higher requirements for RS. Firstly, some important theoretical issues need to be addressed, such as RS information theory, spectral imaging mechanism, electromagnetic radiation transmission model. Secondly, the resolution power of RS instruments and their ability to utilize information needs to be improved. Finally, more detailed and richer RS information is needed during application. Of all these requirements, higher resolution, spectrum resolution, time resolution and further applications of RS are extremely important. While quantum remote sensing (QRS) performs very well in these aspects. QRS study was began in March, 2000, the concept was proposed in early 2001, then QRS technology researches began. The paper firstly introduces its background, concept and research status, its differences and advantages. Then it elaborates QRS research theoretical basis, information mechanism, quantum spectrum imaging research progress of QRS imaging processing. Besides, it emphasizes QRS imaging experimental process, based on which, technical solutions and design of satellite borne QRS active imaging technology and quantum laser radar engineering prototype were proposed, providing technical basis for their application. QRS imaging technology can significantly improve the signal-to-noise ratio and space resolution. Finally, the paper summarizes the researches over the past nineteen years and plans for the future.

Since Professor Siwen Bi proposed quantum remote sensing (QRS) in early 2001, the first QRS imaging prototype was developed after many stages of researches. Based on the results, our group has also undertaken in-depth theoretical and algorithmic experiments on QRS image processing. It’s both a quantum system simulation algorithm, preparing for the future quantum physical devices and calculation technology, and an expansion of quantum theories to RS image processing fields. It combines quantum mechanics theory and RS image processing technology, which introduces a new research direction for RS image processing technology. Now our researches achievements include a quantum denoising algorithm theory and simulation, a quantum enhancement algorithm theory and simulation, and a quantum segmentation algorithm theory research and simulation. A RS denoising algorithm based on the quantum-inspired concept is proposed for image denoising. Key benefits of the algorithm, which include improvements in transmission and accuracy, are demonstrated experimentally. Experiments showed that the peak signal to noise ratio (PSNR) for the proposed algorithm is improved by over 2dB and the edge retention index (EPI) is 0.1 higher than that for common methods. Given the low contrast ratio and brightness as well as insufficient detail for some RS images, a quantum algorithm based on the combination of a quantum inspired and unsharp masking to enhance and segment the RS image data was proposed. Results showed that the contrast ratio and brightness of images processed by the quantum algorithm improved, the image entropy and peak signal to noise ratio is higher.
