The millimeter-wave (MMW) radar detection technology has the advantages of strong penetration, high resolution, strong anti-interference ability, and high detection accuracy. It can maintain high-precision monitoring all day long. MMW radar chips can effectively use key algorithms such as static object elimination algorithms to eliminate false target interference, effectively classify living bodies and other objects, and realize effective monitoring of living bodies. However, the existing non-contact vital signs monitoring radar has harsh monitoring conditions and slow early warning speed, and it is temporarily unable to meet the requirements of emergency warning such as detecting cardiac arrest. Machine learning can provide new ideas in the design of algorithms and break through the limitations of existing algorithms. This project intends to adopt the following research methods:
- Research the data receiving process: After receiving the original data from the radar chip, the data format is first sorted, and the data is updated every second; then the data is down-sampled in the fast time and slow time dimensions to ensure that no valid information is lost under the premise of reducing the amount of data calculation.
- Research the traditional algorithm processing calculation process: remove the interference of the static background in the environment, determine the position of the human target; calculate the phase and phase difference, and superimpose the phase difference between the distance door where the person is located and the adjacent distance door to improve the signal-to-noise ratio ; Filter out high-frequency interference signals with the low-pass filter; perform FFT spectrum estimation, according to the FFT results, find peaks in the respiratory frequency range, and find the center of gravity and sliding average to obtain the respiratory frequency; suppress the respiratory high-order harmonics through the attenuation window, At the same time, the high-order harmonics of the heartbeat are used to find the peak again, and the center of gravity and the sliding average are calculated to obtain the heart rate.
- Research the process of machine learning: collect data sets of different vital signs and label the data. Write a suitable convolutional neural network and train it.
- Research result output process: The result-level fusion of meaningful information such as the position of the human target, the real-time phase change waveform, real-time heartbeat, and respiration output by the traditional algorithm and the information output by the machine learning.
