Passive type radar evaluation system　

With this system, you can measure the distance accuracy and the reception sensitivity of radar which is used for avoiding the car collision.

As the dielectric waveguide is used for the delay line,
(1)The transfer mode is a single mode unlike the metal waveguide. Even if the frequency differs, the transmission delay time is constant.
(2) Dielectric waveguide is not metal, there is no reflection of the electric wave from waveguide.
(3) It can be changed the value of the radar cross section due to the super low loss.
