HB100 is the use of microwave Doppler radar module (Doppler Radar) design principles of the microwave detector moving objects, mainly used in automatic door control switches, security systems, ATM ATM automated video control systems, automatic train signal, etc. place. HB100 is the standard 10.525GHz microwave Doppler radar detector, this detection method compared with other detection methods have the following advantages:
1, non-contact detection;
2, independent of temperature, humidity, noise, air, dust, light and other effects, suitable for harsh environments;
3, anti-RF interference ability;
4, the output power is small, do not constitute harm to the human body;
5, long-distance: detection range of over 20 meters.
Doppler principle Summary: Doppler theory based on time, when the radio wave hits an object in the process of moving the wave is reflected, with the frequency of the reflected wave will hit the moving state of the object changes. If the position of the object fixed radio waves are encountered, then the frequency of the reflected wave and transmitted wave frequency should be equal. If the object moves toward the launch, the reflected waves will be compressed, which means that the frequency of the reflected wave will increase; conversely frequency of the wave is reflected back will be decreased.
According to the design principle of doppler microwave detector medium by the FET DRO microwave oscillation source (10.525GHz), power divider, the transmitting antenna, receiving antenna, mixers, detectors and other circuits (Fig. 2). Transmitting microwave transmitting antenna outwardly directed, is reflected by the object is encountered, the reflected wave is received by the receiving antenna, to the mixer and then mixed with the oscillation, mixed, low-frequency signal after detection of the response speed of moving objects
