Abstract

Extracting target information from signals of a radar and measurement environments, including: transmitting frequency-modulated continuous wave transmit signal using the radar; receiving reflected signal reflected from a human face at multiple antenna elements; multiplying the transmit signal with the reflected signal using a mixer to produce a mixed signal; passing the mixed signal through a low pass filter to produce a baseband signal including sinusoidal signals; extracting a frequency of each sinusoidal signal from the baseband signal to produce extracted frequencies; and measuring a distance between the human face and the radar using the extracted frequencies.
