System Description
III
● The Smallest Radar Sensor Active Blind Spot Detection System for Light-Duty Vehicle.
● The Radar Object Detection System uses FMCW (frequency modulated continuous wave) radar
technology to detect stationary objects and people in blind spots.
● This advanced system alerts the operator with both visual and audible warnings.
● The system’s capability of being able to determine whether an object is approaching or moving
away from the sensor, helps to limit the number of false detections caused by objects of no
concern encroaching on the detection area.
● The commercial grade heavy-duty system has an IP69K waterproof rating and works perfectly
in all weather conditions.
Object Detection Capability
IV
2
The radar sensor transmits and receive 24 GHz radar signal.
It then process the returned signals to determine if an object has reflected any energy back to the sensor .
Our test condition is Radar sensor (height 1 meter location) with adult person at open side.
1dBsm (dB square meter), “Person reflection” approx.at 1dBsm, “Car reflection” at 10dBsm.
The detection range test should be proceeded at
outdoor. The detection zone has been cleared
of all obstacles.
Any obstacles in the detection zone will interfere with the test.
All dimensions for detection of objects are nominal and very significantly depending on many parameters.
In the case where there are multiple objects in the detection area at various distance and/or angles,
the sensor detects the closest object, which is the most imp
ortant one for collision avoidance.
F
actors Influencing the Detection of Objects
The object properties, location and direction are vey key influences in deterring if an object is detected or not.
S
ize: A large object usually reflects more energy than a smaller object.
C
omposition: Metal is detected better than non-metal materials
S
hape: A flat object is better detected than a complex shape. Variation in relative location and
direction can influence detection.
A
ngle: An object facing directly towards the sensor is detected better than an object that is located
towards the edges of the detection area or at an angle.
G
round condition: Objects on flat, mineral material ground are better detected than on rough or
metal surfaces.
