Wireless analysis device and wireless analysis method

A wireless analysis method comprising:

• reading information on a frequency spectrum of an incoming wave and information on a plurality of edges including a rising edge and a falling edge of a signal included in the incoming wave;
• comparing a power change amount of the frequency spectrum at a first edge of the plurality of edges with a first threshold value for each frequency;
• specifying a frequency range in which the power change amount is larger than the first threshold value;
• setting a second threshold value based on a sum of the power change amount within the frequency range;
• and
• specifying a second edge in which a sum of powers in the frequency range changes over the second threshold value among the plurality of edges, the second edge having different directions of power change from the first edge, by a processor.

A non-transitory computer-readable recording medium storing a program that causes a computer to execute a procedure, the procedure comprising:

• reading information on a frequency spectrum of an incoming wave and information on a plurality of edges including a rising edge and a falling edge of a signal included in the incoming wave;
• comparing a power change amount of the frequency spectrum at a first edge of the plurality of edges with a first threshold value for each frequency;
• specifying a frequency range in which the power change amount is larger than the first threshold value;
• setting a second threshold value based on a sum of the power change amount within the frequency range;
• and
• specifying a second edge in which a sum of powers in the frequency range changes over the second threshold value among the plurality of edges, the second edge having different directions of power change from the first edge.
