摘要： The present invention is to perform position estimation in relation to a vehicle and a key module by using an ultra-wideband (UWB) and, specifically, relates to a method and system for precise position estimation for a vehicle, whereby position can be estimated, with effects minimized that result from the type of the vehicle and the quality of exterior metal of the vehicle. The method for precise position estimation for a vehicle over a UWB comprises the steps of: receiving, by an LIN transceiver, a position estimation-related signal delivered from an internal part of a vehicle, and transmitting the signal to a UWB transceiver to start the position estimation; the control unit measuring a predetermined number of times reception signal delays occurring in relation to a UWB tag, while turning on or off the switch of each of M antennas at predetermined time intervals; determining antennas at which the value of a corresponding reception signal delay measured the predetermined number of times is lower than a preset threshold; measuring the distances between the determined antennas and the distances between each of the antennas and the UWB tag; determining position angles with respect to the UWB tag by using a two-way ranging (TWR) positioning method on the basis of the distances between the antennas and the distances between each of the antennas and the UWB tag; measuring the distances between the UWB tag and UWB anchors measured using a triangulation method according to the M anchors and UWB tag; and estimating the position of the UWB tag on the basis of the position angles with respect to the UWB tag and the distances between the N UWB anchors and the UWB tag.

摘要： Disclosed is herein an antenna performance tester including: a horizontal rotor 200 rotatable about a shaft part 110 to which a DUT holder 300 is detachably coupled; and a vertical rotor 500 to which a reference antenna holder 400 is detachably fixed and which is spaced apart from a side surface of the DUT holder 300, is installed perpendicular to the horizontal rotor 200, and is rotatable about a virtual central point lying at the center. The antenna performance tester is advantageous in that: a reference antenna measures an RF while performing transmission and reception with respect to a DUT in all directions at a constant distance from the DUT; extension and replacement are possible depending on a frequency to be measured; and an influence of reflected waves is minimized at RF measurement, antenna performance can be simply tested in an anechoic chamber or even in a semi-anechoic chamber.
