    Abstract: A radar device includes a radar unit, a signal processing unit, a GPS receiver, and a storage unit. The signal processing unit acquires, for each target, a distance (R) to the target and a relative velocity (Veff) between the radar unit and the target when the radar unit is moving. The signal processing unit separately detects positions of a plurality of targets by using a separation algorithm in which a difference between the relative velocities (Veff) is used. When the radar unit is stopped, the signal processing unit corrects the position of each target detected when the radar unit has been moving, based on a current position of the radar unit stored in the storage unit, and identifies the positions of the plurality of targets.

    Abstract: An arithmetic circuit according to the present disclosure performs a signal value acquisition step of acquiring X-axis bending values, Y-axis bending values, and twisting values at respective one or more first times before an impact time identified in a time identification step and at respective one or more second times after the impact time; and a first calculation step of calculating one or more parameters indicating a state of an object to be measured at the impact time by multiplying a plurality of the X-axis bending values, a plurality of the Y-axis bending values, and a plurality of the twisting values acquired in the signal value acquisition step by a matrix.

    CPC classification number: G06F7/76

    Abstract: A data processing apparatus includes an arithmetic circuit that performs an acquiring step of acquiring swing data indicating relationship between a physical quantity concerning an amount of deformation of an object to be measured and time, a determining step of determining whether the swing data indicates the physical quantity concerning the amount of deformation of the object to be measured, which occurs when the object to be measured is swung, to determine whether the swing data is to be deleted, and a deleting step of deleting the swing data if it is determined that the swing data does not indicate the physical quantity concerning the amount of deformation of the object to be measured, which occurs when the object to be measured is swung.

    CPC classification number: G01B7/16

    Abstract: Provided is a sensor unit including a first sensor portion that detects deformation of a measuring target object and a second sensor portion that detects deformation of the measuring target object, in which in a state in which the first sensor portion and the second sensor portion are attached to the measuring target object, the first sensor portion and the second sensor portion are fixed to the measuring target object such that the measuring target object is disposed between the first sensor portion and the second sensor portion in a first direction, and a physical property value of the first sensor portion and a physical property value of the second sensor portion are changed according to first deformation of the measuring target object.
