Publication number: 20230213599Abstract: Disclosed is an inverse estimation-based radius calculation method and system for ferromagnetic target detection. The calculation method includes a data acquisition step and a ferromagnetic target detection radius calculation step. Distrubance of a scale model to power frequency electromagnetic waves is used to inversely estimate a corresponding ferromagnetic target detection radius. Inverse estimation is performed separately for an air layer and a sea water layer according to test results of multiple scale model tests and in consideration of both a stationary state and a motion state of the scale model, so as to acquire a ferromagnetic target detection radius calculation formula. Weights of factors such as mass, speed, depth, and height are great in inverse estimation, so that inverse estimation precision is improved. The majority of background noise interference can be screened out of the power frequency electromagnetic waves.Type: ApplicationFiled: December 30, 2022Publication date: July 6, 2023Inventors: Tianxu ZHANG, Hanyu HONG, Bin TIAN, Yuehuan WANG, Tao ZHANG, Qinghui ZHANG, Cheng YANG, Jiawei WANG, Jiandong TAN

Patent number: 9625611Abstract: The present invention discloses a method for detecting, recognizing, and positioning a zonal underground target in a mountain land environment by detecting a ridge position in the mountain land environment and carrying out energy correction. The method belongs to the interdisciplinary field of pattern recognition, remote sensing technology and terrain analysis. The zonal underground target can cause energy abnormity when the heat field thereof is different from that of a mountain mass, and the heat island effect of the ridge can also cause the energy of the mountain mass to be abnormal. However, the energy abnormity caused by the heat island effect is essentially different from the energy abnormity caused by the zonal underground target in the aspect of mode.Type: GrantFiled: February 10, 2015Date of Patent: April 18, 2017Assignee: Huazhong University of Science and TechnologyInventors: Tianxu Zhang, Cen Lu, Yuehuan Wang, Weidong Yang, Nong Sang, Wenxuan Ma, Longwei Hao
