Abstract
A method and electronic device for motion assisted leakage removal. The electronic device includes a radar transceiver, a sensor, and a processor. The processor is configured to determine that the electronic device is in a first motion state, During the first motion state, the processor is configured to transmit a first set of signals. The processor is also configured to generate a first channel impulse response (CIR) based on the received first set of signals. The processor is further configured to apply a filter that estimates a leakage depicted by the first CIR. During a second motion state, the processor is configured to transmit a second set of signals. Additionally, the processor is configured to generate a second CIR based on the received second set of signals, and apply the estimated leakage from the first CIR to the second CIR to remove leakage from the second CIR.
