The Baotou sandy site in China is an important field the Committee on Earth Observation Satellites radiometric calibration network (RadCalNet), which freely releases bottom-of-atmosphere (BOA) and top-of-atmosphere (TOA) spectral reflectance products range from 400 nm to 1000 at 10 intervals with aid of a set automatic atmospheric parameter measurement devices. However, released TOA BOA are nadir-view reflectance, could produce errors if offset nadir point when they utilized calibrate one...

Configuration design, component sizing, and energy management are intertwined. However, the full potential of hybrid powertrains has not yet been thoroughly investigated due to multi-dimensional design space. Therefore, in this paper, a joint optimization method combining particle swarm (PSO) convex programming (CP) is proposed for first time. In outer loop, PSO algorithm searches optimal powertrain configuration. contrast, size power simultaneously optimized by CP inner loop. A combined...

The on-orbit radiometric calibration of spaceborne sensors is the foundation quantitative remote sensing, and accuracy directly affects quality sensing products. wide swath Chinese ocean color temperature scanner (COCTS) onboard HY-1C satellite makes it difficult to ignore errors caused by viewing angles during calibration. Thus, this paper proposes a cross-calibration method based on bottom-of-atmosphere (BOA) top-of-atmosphere (TOA) spectral band adjustment factors (SBAFs). This...

To obtain more abundant target information for vegetation remote sensing research, the wide field of view (WFV) GaoFen-6 (GF-6) satellite utilizes eight bands, including four new bands. Unfortunately, it finds unavailable reference bands from well-calibrated sensors to implement radiometric cross-calibration WFV sensor these which severely affects quality estimation and degradation detection WFV. Therefore, taking Dunhuang calibration site (DRCS) in China as transfer platform treating...

The wide field of view (WFV) imaging system the GaoFen-6 (GF-6) satellite processes four popular spectral bands [blue, green, red, and near-infrared (NIR)] new (costal, yellow, two red edges). However, corresponding reference for these eight from one sensor are insufficient in cross-calibration process WFV; therefore, current methods should be improved. To address this problem, Moderate-Resolution Imaging Spectroradiometer (MODIS), which has high radiometric performance with aid an onboard...

To obtain more abundant target information, the panchromatic and multispectral sensor (PMS) of GaoFen-4 (GF-4) satellite utilizes five different integration times. The optimal approach for carrying out integrated processing absolute radiometric calibration difference minimization PMS images over these times remains an important issue. Therefore, taking Dunhuang site (DRCS) in China as radiometric-transfer platform treating Moderate-resolution Imaging Spectroradiometer (MODIS) Landsat-8...

As the core and foundational technology, on-orbit radiometric calibration of a space-borne sensor is great importance for quantitative remote sensing applications. multi-camera mosaic imaging sensor, however, currently available method cannot carry out integrated processing absolute relative correction simultaneously between cameras, influencing accuracy Therefore, taking GaoFen-1 (GF-1) wide-field-of-view (WFV) as an example in this research, innovative proposed to overcome bottleneck....

This paper introduces an improved particle swarm optimisation algorithm (IPSO), to select satellites rapidly in multi-GNSS marine positioning. The traditional (PSO) may be trapped into local optimisation. To avoid the disadvantage, proposed uses linear inertia weight factor and two functions of immune system, i.e. memory function self-regulatory function. Several experiments are carried out by adopting real survey data collected SiNan receiver that is installed on Snow Dragon scientific...

In the process of radiometric calibration, corrections for bidirectional reflectance distribution functions (BRDFs) and spectral band adjustment factors (SBAFs) are crucial. Time-series MODIS images commonly used to construct BRDFs by using Ross–Li model in current research. However, BRDF is based on linear relationship between kernel models unable take into account nonlinear them. Furthermore, when SBAF difference, a radiative transfer often used, but it requires many parameters be set,...
