“…This effect appears to be strong, since it overcomes what we would expect from pixel size: the Sofradir pixels being only 15 μm in size which could favour energy diffusion to the neighbouring pixels, while H1RG pixels are 18 μm. It is however supported by the well-known higher cross-talk in the HxRG: usual cross-talk values for Sofradir detectors are below 3% (Fieque et al, 2019), while for H1RG values between 4 and 10% were standard until recent improvements (Prieskorn et al, 2013), which are not implemented in the detector we used though.…”

The European Space Agency (ESA), in collaboration with the European Commission (EC) and EUMETSAT, is developing a space-borne observing system for quantification of anthropogenic carbon dioxide (CO 2 ) emissions. Forming part of the EC's Copernicus programme, the CO 2 monitoring (CO2M) mission will be implemented as a constellation of identical satellites, to be operated over a period of at least 7 years and measuring CO 2 concentration in terms of column-averaged mole fraction (denoted as XCO 2 ). Each satellite will continuously image XCO 2 along the satellite track on the sun-illuminated part of the orbit, with a swath width of >250 km. Observations will be provided at a spatial resolution of 2 x 2 km 2 , with high precision (<0.7 ppm) and accuracy (bias <0.5 ppm). To this end, the payload comprises a suite of instruments addressing the various aspects of the challenging observation requirements: A push-broom imaging spectrometer will perform co-located measurements of top-of-atmosphere radiances in the Near Infrared (NIR) and Short-Wave Infrared (SWIR) at high to moderate spectral resolution

“…e emergence of various kinds of social media has enabled a large amount of private information to be transmitted on the open network [1]. In recent years, with the rapid development of space science and information technology [2][3][4], massive amounts of remote sensing image information need to be transmitted in an open network and shared service environment [5]. Remote sensing images play an important role in agriculture, land, water resources, minerals, weather, and air pollution monitoring, disaster prevention and mitigation, national defense, and many other fields, providing a solid technical guarantee of the sustainable development of the national economy [6].…”

A Novel Multiband Remote-Sensing Image Encryption Algorithm Based on Dual-Channel Key Transmission Model

With the rapid development of remote sensing technology, satellite remote sensing images have been involved in many areas of people’s lives. Remote sensing images contain military secrets, land profiles, and other sensitive data, so it is urgent to encrypt remote sensing images. This paper proposes a dual-channel key transmission model. The plaintext related key is embedded into the ciphertext image through bit-level key hiding transmission strategy, which enhanced the ability of ciphertext image to resist known-plaintext attack and chosen plaintext attack. In addition, a multiband remote sensing image encryption algorithm based on Boolean cross-scrambling and semi-tensor product diffusion is designed. Firstly, the pixel positions of each band of the remote sensing image are disturbed. Then, the random sequence generated by the four-dimensional chaotic system is processed and deformed to obtain a Boolean matrix. Based on the generated Boolean matrix and certain rules, the cross-confusion between the bands is carried out. Finally, the semi-tensor product operation is used in the diffusion process. Simulation results and experimental analysis show that the proposed algorithm obtains a larger key space and has stronger antiattack ability than other remote sensing image encryption algorithms. It can meet the security transmission of multiband remote sensing image in open space.
