MEASUREMENT APPARATUS AND MEASUREMENT METHOD
First Claim
1. A measurement apparatus comprising:
- a first Doppler sensor which outputs a first transmission signal and receives a first Doppler signal, that is the first transmission signal returned after being reflected by an impacting object;
a timing detection unit that detects an impact timing, that is a moment when an impacted object is impacted by the impacting object;
an impacting object speed computing unit that computes a speed of the impacting object based on the first Doppler signals obtained from the detected impact timing to a timing before a predetermined period; and
an imaging unit that images the impacted object immediately after the impact so as to be used for computing a motion state of the impacted object, based on the computed speed of the impacting object.

Abstract
A measurement apparatus includes a first Doppler sensor which outputs a first transmission signal and receives a first Doppler signal, that is the first transmission signal returned after being reflected by an impacting object, a timing detection unit that detects an impact timing which is a moment when an impacted object is impacted by the impacting object, an impacting object speed computing unit that computes a speed of the impacting object based on the first Doppler signals obtained from the detected impact timing to a timing before a predetermined period, and an imaging unit that images the impacted object immediately after the impact so as to be used for computing a motion state of the impacted object, based on the computed speed of the impacting object.

7. A measurement method by a measurement apparatus having a Doppler sensor, a timing detection unit, a computing unit and an imaging unit, the method comprising the steps of:
-
the Doppler sensor outputting a transmission signal and receiving a Doppler signal, that is the transmission signal returned after being reflected by an impacting object; the timing detection unit detecting an impact timing, which is a moment when an impacted object is impacted by the impacting object; the computing unit computing a speed of the impacting object based on the Doppler signals obtained from the detected impact timing to a timing before a predetermined period; and the imaging unit imaging the impacted object immediately after the impact so as to be used for computing a motion state of the impacted object, based on the computed speed of the impacting object.
