Patent number: 11977175Abstract: Provided is a technology for increasing accuracy of position estimation by estimating a position of a signal source based on an error due to altitudes of a sensor and a signal source and an error due to a pitch of an aircraft as well as an error due to curvature of the earth. At this time, a position estimation method may include receiving measurement data from a plurality of sensors, estimating first position data of the signal source based on the measurement data, identifying an altitude error of the first position data, and estimating second position data that is data obtained by correcting the first position data based on the altitude error.Type: GrantFiled: September 21, 2021Date of Patent: May 7, 2024Assignee: AGENCY FOR DEFENSE DEVELOPMENTInventors: Sang Won Kim, Dong Keun Lee, Jeung Min Joo, Jung Hoon Kim, Sung Jin Jo

Publication number: 20210394231Abstract: The present invention relates to a method for preparing a porous polymer film having a controlled pore depth, and a porous polymer film prepared thereby. A method for preparing a porous polymer film according to the present invention allows the pore depth of a porous film to be controlled simply and at a low cost, and thus allows adjustment of the light reflectance of the prepared film. A large-area film can be prepared by means of a simple method and thus can be applied to various industry fields. Films having different reflectance can be prepared and thus can be applied as low-reflection and high-reflection films for solar cells, and also as a low-reflection or high-reflection thin polymer film in the construction field or material and equipment field.Type: ApplicationFiled: October 30, 2019Publication date: December 23, 2021Applicant: Industry-University Cooperation Foundation Hanyang UniversityInventors: Dong Rip KIM, Han Min JANG, Sung Won JO
