Abstract: A reservoir bank landslide susceptibility evaluation method. The method includes the following steps: S1, acquiring geophysical parameters; S2, calculating stability of a reservoir bank after impoundment through a static geological evaluation model according to the geophysical parameters; S3, obtaining an average displacement velocity in a geographic coordinate system according to single look complex (SLC) images after impoundment; and S4, according to the average displacement velocity in the geographic coordinate system and the stability of the reservoir bank after impoundment of the reservoir, obtaining a reservoir bank landslide susceptibility grade. According to the method, a problem that present landslide susceptibility evaluation methods all adopt a single model to evaluate landslide susceptibility, which has low evaluation accuracy of the landslide susceptibility is solved.

Abstract: A method for calculating a sensitivity of a displacement of Synthetic Aperture Radar (SAR) along line-of-sight direction to a slope gradient and a slope aspect is provided, comprising: obtaining SAR data and Digital Elevation Model (DEM) data covering slope bodies, and extracting a local incident angle of an image by utilizing a satellite side-looking imaging principle; carrying out geometric distortion on the slope bodies under ascending and descending orbits by utilizing the local incident angle, to obtain specific locations of geometric distortion areas under ascending and descending orbit; calculating sensitivities of detections to changes of the slope gradient and the slope aspect under ascending and descending orbits according to the extracted parameter information of the SAR satellite in ascending and descending orbits and satellite heights, and dividing a sensitivity distribution by combining the sensitivity and the specific locations of the geometric distortion.

Abstract: An ice detector includes an icing assembly that includes a transparent icing rod with an illuminating element is disposed therein and having an ice accretion surface and a support structure. The icing rod has at least one visual sensor configured to obtain an image of the ice accretion surface; a controller electrically connected to the visual sensor and including an image contrast module configured to compare the obtained image with an initial image so as to judge whether ice is formed on the ice accretion surface of the icing rod. The icing assembly includes a refrigerating element respectively connected to the icing rod and the support structure. The refrigerating element may perform active refrigeration for the icing rod, reduce the surface temperature of the icing rod and facilitate the ice detector detecting ice accretion before ice is formed on a wing/nacelle.
