Transparent method of reproducing video and multi-path millimeter wave imaging radar system

摘要

PROBLEM TO BE SOLVED: To provide an imaging radar system capable of reproducing a transmission image of an object at high speed, and probing surely regardless of existence an obstacle hindering a propagation route of a radio wave. ;SOLUTION: This system is equipped with a radar body 14 having an oscillating circuit and a receiving circuit, and an array antenna 12 connected respectively to the oscillating circuit and the receiving circuit through antenna element switchers 20T, 20R and comprising a transmitting antenna element row and a receiving antenna element row for transmitting and receiving the radio wave in a millimeter wave band. The array antenna is aligned on the first focal line position, and an elliptic cylindrical surface reflecting mirror 10 rotatable and drivable around the first focal line, capable of turning and scanning the second focal line is installed, and a controller 24 for controlling the antenna switcher so as to select all combinations between the transmitting antenna elements and the receiving antenna elements synchronously with a rotation signal from the elliptic cylindrical surface reflecting mirror is installed. In addition, an operation part 54 for performing image reproduction processing based on received signals detected relative to each rotation angle signal of the elliptic cylindrical surface reflecting mirror, and operating a transmission image output signal of the target is installed.;COPYRIGHT: (C)2003,JPO
