<p>PROBLEM TO BE SOLVED: To reduce a dead zone and ringing of an electromagnetic radar device, and to improve the discrimination ability of a deep fine fault. SOLUTION: In this electromagnetic radar, in which a transmission antenna A comprising two element conductors 1a having feeding points 13 positioned on the antenna centers respectively, and a reception antenna B comprising two element conductors 1b having network connection points 14 positioned on the antenna centers respectively are installed in parallel, resistances 4a, 4b loaded on square end parts of element conductors 1a, 1b on one side of each antenna, and resistances 4a, 4b loaded on square end parts of element conductors 1a, 1b on the other side forming a pair with one side are electrically connected, and the value of each resistance 4a is set larger than that of each resistance 4b loaded on the conductor end part facing to the outside of the electromagnetic radar.</p> |
