DELAY TIME DIFFERENCE MEASURING APPARATUS, PHASED ARRAY ANTENNA DEVICE, AND DELAY TIME DIFFERENCE MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To measure a delay time difference among respective signal processing systems containing a previously unclear part, even after assembling a phased array antenna device that cannot be disassembled.;SOLUTION: A delay time difference measuring apparatus is configured so that a field intensity measuring device 12 for measuring electric field intensity of a high frequency signal received by a receiving antenna 11 is provided, and that a delay time difference estimation part 23 estimates a delay time difference between two signal processing systems selected by a signal processing system selection part 21, from a variation cycle of the electric field intensity measured by the field intensity measuring device 12.;COPYRIGHT: (C)2015,JPO&INPIT
