24GHz Doppler Radar Velocity Detection Radar Sensor Description
ZLYTR22 narrow-wave velocity measurement radar is a millimeter wave radar module integrating microstrip antenna, radio frequency circuit and signal processing circuit, directly output target speed information. It can be used to detect long-distance vehicle speed up to 320 meters, using integrated RF chip, high frequency stability, speed measurement accuracy ≤1KM/h.
It is widely used in speed warning of highway, urban trunk line, city-county level highway, urban and rural trunk road and other roads, as well as road curve and intersection warning.
