Ultra-wideband-based fall detection

A method of operating an electronic device, the method comprising:

• transmitting and receiving ultrawide band (UWB) radar signals;
• generating a plurality of UWB channel impulse response (CIR) frames based on the transmitted and received UWB radar signals;
• storing the plurality of UWB CIR frames within a buffer;
• preprocessing the plurality of UWB CIR frames stored within the buffer;
• performing range doppler calculations on the preprocessed plurality of UWB CIR frames;
• performing, based on a result of the range doppler calculations, a range bin selection operation;
• detecting a human within a detection area of the electronic device based on a result of the range bin selection operation and based on removing one or more non-human artifacts;
• performing, based on the detection of the human within the detection area of the electronic device, a motion detection operation;
• and
• performing, based on a result of the motion detection operation, a fall detection operation.

A non-transitory computer readable medium embodying a computer program, the computer program comprising program code that, when executed by a processor of a device, causes the device to:

• transmit and receive ultrawide band (UWB) radar signals;
• generate a plurality of UWB channel impulse response (CIR) frames based on the transmitted and received UWB radar signals;
• store the plurality of UWB CIR frames within a buffer;
• preprocess the plurality of UWB CIR frames stored within the buffer;
• perform range doppler calculations on the preprocessed plurality of UWB CIR frames;
• perform, based on a result of the range doppler calculations, a range bin selection operation;
• detect a human within a detection area of the device based on a result of the range bin selection operation and based on removing one or more non-human artifacts;
• perform, based on the detection of the human within the detection area of the device, a motion detection operation;
• and
• perform, based on a result of the motion detection operation, a fall detection operation.
