DETECTION DEVICE, DETECTION METHOD, AND DETECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To separate incoming waves coming from a plurality of azimuths from each other regardless of the shape of an array in a detection device.SOLUTION: In a detection device 1, each of a plurality of transmission elements Aof a transmission element array 10 transmits a pulse wave Pof a frequency set in the accordance with the azimuth direction of the arrangement of each transmission element A. In the detection device 1, an arrival direction estimation unit 31 estimates the arrival direction of the incoming wave on the basis of a reception signal acquired by a plurality of reception elements Awith a plurality of timings.
