Electronic device for expanding sensing bandwidth by integrating plurality of channel impulse responses, and control method therefor

An electronic device comprising:

• a first communication circuit;
• a second communication circuit;
• and
• at least one processor operatively connected to the first communication circuit and the second communication circuit,
• wherein the first communication circuit is configured to:
• receive, in a first band, a first reflection signal reflected by at least one object, and
• based on the received first reflection signal, obtain a first channel impulse response corresponding to the first reflection signal,
• wherein the second communication circuit is configured to:
• receive, in a second band, a second reflection signal reflected by the at least one object,
• based on the received second reflection signal, obtain a second channel impulse response corresponding to the second reflection signal, and
• obtain a third channel impulse response based on a first calculation using the second channel impulse response, a first frequency of the first band and a second frequency of the second band, and
• wherein the at least one processor is configured to:
• obtain a fourth channel impulse response based on the first channel impulse response and the third channel impulse response.
