Design of Receiver Frontend with Deep Neural Network for Doppler Radar Heart Rate Detection

This article presents a 24GHz doppler radar detection, high gain, receiver frontend for cancelling random heart rate sensing by deep neural network (DNN) in noncontact healthcare applications. The proposed heart rate sensing with algorithm, different frequencies and phase offsets are synthesized and integrated with simulation to train the DNN analysis. This article promoted integrated circuit in LNA, Mixer and bandpass filter with array antenna for contribution of doppler radar heart rate detection Experimental results demonstrate that the proposed idea can alleviate the noise cancellation and stable signal when body movement or normal respiration motion for 24GHz doppler radar vital sign detection.
