Abstract: An obstacle monitoring system includes: a sensing means; a first obstacle detection means; and a control means for selectively executing a plurality of control modes including a first control mode in which a moving speed of a moving body is a first moving speed and a sensing field of view of the sensing means is a first field of view, and a second control mode in which a moving speed of the moving body is a second moving speed and a sensing field of view of the sensing means is a second field of view. When the first obstacle detection means detects the obstacle while the control means is executing the first control mode, the control means executes the second control mode in such a way as to capture the obstacle within the second field of view.

Abstract: For increasing measurement precision while suppressing cost increase when measuring a permittivity of an object using a radio wave, an object detection apparatus includes a transmission unit projecting a radio wave toward a target object by using a transmission antenna, a reception unit receiving the radio wave reflected by the target object by a reception antenna and generating an intermediate frequency signal, and an arithmetic apparatus. The arithmetic apparatus computes a reflection amplitude of the target object from the intermediate frequency signal, computes a reflectance from the reflection amplitude, computes a complex permittivity absolute value of the target object from the computed reflectance, computes a depth position of the target object from the reflection amplitude, computes a thickness of the target object from the depth and the reflection amplitude, and computes a permittivity of the target object from the reflection amplitude, the complex permittivity absolute value, and the thickness.
