WARNING: Not to Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so
could lead to serious injury or death. This device does not include the self-
checking redundant circuitry necessary to allow its use in personnel safety
applications. A sensor failure or malfunction can cause either an energized or
de-energized sensor output condition.
Overview
The Q-Global sensor emits a well-defined beam of high-frequency radio waves
from an internal antenna. Some of this emitted energy is reflected back to the
receiving antenna. Signal processing electronics determine the distance from
the sensor to the object based on the time delay of the return signal. The
sensor can be configured to two independent sensing zones. The two sensing
zones are factory pre-set to default distance; The sensor is plug-in ready for
immediate operation. The sensitivity is precalibrated at the factory, assuming
that the sensing field will be clear of obstacles.
Product Usage Instructions
Overview
The Q-Global sensor emits high-frequency radio waves from an internal antenna
and processes the reflected signals to determine the distance, angle, and
speed of the target. It can detect static and moving objects within a range of
1 to 60 meters.
Installation
Ensure the sensor is connected to a 12V/24V DC power source using the provided
8-pin waterproof terminal. The sensor is plug-in ready for immediate
operation.
Beam Patterns
- Weak Object(RCS = -10)
- Rider (RCS = 0)
- Car(RCS = 10)
- Larger Truck(RCS = 20)
Operating Instructions
The sensor operates using FMCW radar technology with an operating frequency of
77-81GHz. Ensure the sensor is positioned to have a clear field of view
without obstacles within its detection range.
Window Placement
If placing the sensor behind a window, ensure the configuration is tested and
the distance from the sensor to the window is determined and controlled. Note
that there may be a 20% signal reduction when the sensor is behind a window.
Windows
The Q-Global sensor can be placed behind a glass or a plastic window, but
the configuration must be tested and the distance from the sensor to the
window must be determined and controlled prior to installation. There is
typically a 20% signal reduction when the sensor is placed behind a window.
Polycarbonate at 2mm thickness performs well in most situations, but the
performance depends on filler materials. Thinner (0 to 1.5mm) windows have
high reflection. The amount of reflection depends on the material, thickness,
and distance from the sensor to the window. Locate the sensor in a position of
minimum reflection from the window, which will repeat every 1.9 mm of distance
between the sensor and the window. The position of maximum reflection from the
window repeat between the minimums, and decrease in effect until the window is
approximately 150mm away. Consult the factory for pre-tested window materials
which can be used at any distance without issue. Additionally, the face of the
window should be protected from flowing water and ice by use of a flow
diverter or hood directly above the window. Falling rain or snow in the air in
front of the window, light water mist, or small beads on the face of the
window are typically not an issue. However, a thick, continuous surface of
water or ice directly on the face of the window can be detected as a
dielectric boundary.

System function
- Left green light: the left lane length is detected: 20+vehicle_speed/25m, width: 2m-6m that detected moving objects.Fox example, the radar detect 20m forward when the vehicle speed is 0 km/h, the detect distance will be 24m when vehiclespeed is 100(100/25m=4m).
- Right green light: the right lane length is detected: 20+vehicle_speed/25m, and the width is 2m-6m that detected moving objects.
- Middle digital tube: the distance to the nearest object in the middle lane the width#2m,and the length is 2m-90m.
- Simultaneous yellow lights on both sides: safe following distance warning (vehicle_speed/3)m.
- Simultaneous red lights on both sides: collision warning (collision time <3s, vehicle speed>20KM/H).
- (The current version 1.0 is recommended to be used at a speed of 20KM/H or above, and the recognition rate of static obiect collision detection is not high).

Note:
- The radar is centred on the left and right, and the area extending 0.7m outward is the current motorcycle lane; the 0.7m on both sides of the radar is the left and right adjacent lanes.
- The lane width defined by radar detection is 1.4m, the lane position may be offset when the vehicle body is not parallel to the actual lane line on the road surface.
