Page 3: Overview
Overview This document mainly describes how to use the module of MR60BHA1 to develop a product and explain the problems should be paid attention to during the process. The manual can help to reduce the design cost and increase the stability of the product, which can improve the efficiency of development. -
Page 4: Working Principle
Working principle radar transmits a 60 G-band millimeter wave signal, and the measured target reflects the electromagnetic wave signal,and demodulates the transmitted signal, and then processes it through amplification, filtering, and ADC to obtain echo demodulated signal data. In the MCU unit, the amplitude, frequency, and phase of the echo signal are calculated, and the target parameters ( sleep quality, breathing, turning over, body movement , etc.) are measured and the scene evaluation is finally realized. -

Page 6: Static Protection
Static Protection Radar products have static-sensitive circuits inside, which are prone to electrostatic hazards. Therefore, it is necessary to fully protect against static electricity during transportation, storage, work and handling. Do not touch and grab the radar module antenna surface and connector pins. -
