Abstract
A detection apparatus includes: a plurality of accelerometers configured to be installed on respective positions of the architectural structure which are different in height from each other and separately measure an acceleration value generated in the architectural structure; and a computer configured to perform computation by using acceleration values measured by the plurality of accelerometers and detect collision of a flying object (airplane) against the architectural structure when a ratio between the acceleration values measured by the plurality of accelerometers exceeds a first threshold value.
