摘要： An object detection method and apparatus in which, in order to distinguish only an echo wave which is returned back from an object of interest, such as an underground buried object, from those echo waves returned back from another object of objects, the observation signal is divided (an electromagnetic wave as an echo wave) into portions, and the signal portion is converted into a corresponding frequency region to evaluate that spectral distribution and computes frequency parameter values from the spectrum distribution. The object of interest is detected by comparing the reference data of various fields with the parameters of the object of interest, extracting only an echo wave returned back from the object of interest and displaying a corresponding image.

摘要： The object is to provide a brace which allows its installment to an object portion and its detachment therefrom to be carried out easily. In a brace including a brace body 3 which is attachable between attaching object portions of a structure, at each one of opposed end portions of the brace body 3, there is provided a contact attaching portion to be attached to the attaching object portion. The brace body 3 includes an expandable urging mechanism S which can be expanded to urgedly extend the brace body 3 along a longitudinal direction thereof, with the two contact attaching portions attached to the attaching object portions and a prestress introducing mechanism P which can be switched over between a state for introducing a compressive prestress to the brace body 3 along the longitudinal direction thereof and a state for releasing the introduced prestress. At least a state switchover control portion 22 of the prestress introducing mechanism is provided to be exposed outside the brace body 3.
