The electronic device includes at least a first antenna pair comprising a first transmitter antenna configured to transmit signals and a first receiver antenna configured to receive signals, a memory, and a processor. The processor is configured to control the first transmitter antenna to transmit a first signal, generate a channel impulse response (CIR) based on receiving, by the first receiver antenna, a reflection of the first signal, determine a location of at least one leakage peak in the CIR, compare a first segment of taps in the CIR prior to the at least one leakage peak with a second segment of taps in the CIR after the leakage peak, and determine an object is present based on symmetry between the first and second segments of taps."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatuses for object presence detection and range estimation","description":"A method and electronic device for object detection.
