Reliable subpixel impervious surface area (ISA) mapping at medium resolution is essential but difficult due to the complexity of land cover patterns within the urban/peri-urban area. In this letter, we proposed a framework to optimize subpixel ISA mapping performance with adaptive integration of features from spectral, phenological, and spatial dimensions. We utilized the recursive feature elimination...
This abstract presents an emulation and program context reconstruction tool for a real-time high-precision positioning embedded system. This tool records the context of the embedded software in the operation without affecting runtime behavior. The execution procedure is re-created on a host machine off-line through reconstruction. This approach successfully accelerates the debugging and fault diagnosis...
This article presents the scanning mechanism of push-broom satellite antenna working at 140 GHz. Such kind of antenna can be applied into many areas, such as imaging, ocean surveillance and astronomical observation. The feeds are placed at the rotary focus with a spacing of 1.72 cm between two adjacent feeds, and the center distance from the feed to the reflector surface is 14.48 cm. Meanwhile, the...
Ship target detection in optical remote sensing images has attracted more and more attention in the field of remote sensing. The ship target detection technology of optical remote sensing images is vulnerable to many factors, while the real data are difficult to contain various elements. In order to obtain the various situations in the large sea scenes, we develop a simulation system for high-resolution...
We address the problem of vision-based pose estimation for space objects, which is to estimate the relative pose of a target spacecraft using imaging sensors. We develop a novel monocular vision-based method by employing Gaussian process regression (GPR) to solve pose estimation for space objects. GPR is a powerful regression model for predicting continuous quantities, and can easily obtain and express...
