Overview
This document focuses on the use of the radar, the issues that need to be
addressed at each stage to minimise design costs and increase product
stability and improve the efficiency of project completion.
From hardware circuit reference design, radar antenna and housing layout
requirements, how to differentiate between interference and multi-functional
standard UART protocol outputs.
The radar is a self-contained space sensing sensor, consisting of RF
antenna, radar chip and high speed main frequency MCU together with a
module that relies on a stable and flexible superior algorithm architecture
core to solve the user's various scenario detection needs, which can be
equipped with a host computer or host computer to flexibly output detection
status and data, meeting several groups of GPIOs for custom development.
1. Principle of operation
The radar transmits a millimetre wave signal in the 24G band, the measured
target reflects the electromagnetic wave signal and demodulates the
transmitted signal, which is then amplified, filtered and processed by ADC to
obtain the echo demodulated signal data. The amplitude, frequency and
phase of the echo signal are decoded in the MCU unit, which ultimately
