Direction Pointing:
The SS00 is directional in nature. It may be configured to detect and measure the
speed of incoming or outgoing traffic. It then rejects traffic moving in the
opposite direction. Direction of detection is configured via a bit in the MO
variable in the radar.
For optimal performance:
Radar should be mounted as suggested in the section titled “Mounting” earlier
Radar should be pointed into the direction of the oncoming traffic.
Radar should be placed along the size of the road to minimize the angle of the
oncoming traffic to the radar.
o
If radar cannot be placed right along the side of the road, it should be
pointed at least 100-150 feet up the road into oncoming traffic.
The radar may pickup rotating fans. Avoid pointing it at fans or compressors.
Radar should be mounted at least 3 feet high from the road for optimal
performance and at least 5 feet off the ground for maximum pickup distance
Recommended Enclosure for the SS300-OPF:
The SS300-OPF radar needs to be enclosed in a weatherproof enclosure for outside use.
The following needs to be observed for optimal performance:
1. The front face of the radar (with the golden pads) is the antenna and is the face
that must point into traffic.
2. Any cover or window in front of the unit MUST be at least ¼” away from the
face.
3. Do NOT spray any conformal (or other) coating, paint or other substance on the
antenna.
4. The optimum material to use as a front window is Lexan (Polycarbonate) plastic.
5. The optimum thickness of this polycarbonate window is half wavelength of
24.125Ghz or about 3.5 to 3.7mm thick.
a. Alternatively a thin window of any plastic material may be used. The
maximum thickness in this case should be no more than 1 mm (40 mils).
6. Other plastic materials may be used as a front window, but the optimum thickness
will wary with the material’s dielectric constant. Please contact us for details.
Alternatively, you may consider weatherproof version SS300-DFT that is available from
Houston Radar.
