Definitions

  • the present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide a detection device and a detection method capable of confirming the state of a transmission line with a simple configuration.
  • the measurement unit 13 Based on the generated digital signal Ds3, the measurement unit 13 generates amplitude data Ds3a indicating the amplitude of the reflected signal and phase data Ds3p indicating the phase of the reflected signal, and detects the generated amplitude data Ds3a and phase data Ds3p. 14.
  • the bending angle ⁇ yz can be detected based on the reactance X.
  • the storage unit 15 stores the reference value SZ of the impedance Z.
  • the reference value SZ is set in advance based on the impedance Z calculated by the detection unit 14 when a measurement signal of a specific frequency is output to the target transmission line whose bending angles ⁇ xy and ⁇ yz are zero degrees.
  • the reference value SZ is a plurality of values calculated by the detection unit 14 for each frequency of the measurement signal when measurement signals of a plurality of specific frequencies are respectively output to the target transmission line whose bending angles ⁇ xy and ⁇ yz are zero degrees. may be preset based on the impedance Z of .
  • the detection unit 14 detects changes in the bending angles ⁇ dxy and ⁇ dyz and changes in the curvature of the target detection line based on the calculated difference DZc.
