Page 7: Principle Of Operation
Principle of Operation FMCW Radar The dual FMCW radars in the Speedlane Pro modulates the frequency of the transmit signal in a linear fashion. The difference between the frequencies of the local oscillator and the signal returned from the target is proportional to the time delay between these signals and thus is proportional to the distance to target. -
Page 8: Radar Detection Zone
The patent pending dual radars setup “virtual speedtraps” in 0.375” increments in front of the Speedlane Pro which allows measurement of speed, direction of travel and length of each vehicle. -
Page 9: Radar Pointing
d. Metal targets have larger cross section than non-metallic targets (like humans, animals, plastics etc.) e. Metal surfaces joined at a 90-degree angle create perfect reflector. f. Perfectly flat metal surface at an angle other then 90 degrees may reflect the radar beam away and result in a weak target. -
Page 10: Choosing A Ctc Value
1. You may issue this command during the setup when road is clear of the vehicles so you do not have to wait for an automatic clutter map adjustment to take place. This is especially handy in applications where a long CTC is required. A snapshot command temporarily overrides long CTC value and speeds up clutter map reconstruction. -
Page 11: User Configurable Detection Lanes
Houston Radar Binary protocol. The same protocol is used to communicate to all radars (Doppler and FMCW) produced by Houston Radar. Please contact us for a “C” or “C#” SDK (software development kit) if you wish to utilize this feature. -
Page 12: Radar Mounting
The user must perform a “camera view” check using the included snapshot camera to validate that the radar beam is pointed correctly. Installation must also ensure that the Speedlane Pro is rigidly mounted. Support structures that are affected by wind are not a good choice. Swaying action changes radar’s field of view and affects the performance. -
Page 13: Location
See section “Leveling the Speedlane Pro during installation:” for details on using the onboard level meter to assist with ensuring that the unit is parallel to the road surface. Using a 3/16” hex key loosen the 4 hex bolts about 2 to 3 turns till the clamps allow the tube to rotate freely. -
Page 14: Setback And Mounting Height
Setback and Mounting Height In the side fire multi-lane installation the radar must be mounted in such way that it may see over the top of the closer vehicles. This requires it to be mounted higher than the tallest vehicle it will encounter in a closer lane. An exception to this rule is a situation where you are detecting only the closer lane, e.g. - Page 15 Speedlane Pro Installation Table (in feet) Offset from 1 Recommended Height Minimum Height (ft) Maximum lane (ft) Height (ft) Page 15 of 50...

Page 18: Sighting Camera
In this example, the Speedlane Pro was mounted with a 40 foot setback from the closest lane and about 20 feet high. The far lane is about 135 feet away. Note the concrete barrier after the 2 lane. - Page 19 Click the “Take Photo” button to take a snapshot of the radar view of the road. This is a very convenient feature of the SpeedLane to verify proper pointing both in the vertical and horizontal direction. Ensure you are pointed as close to 90° to the passing traffic as possible for best results.

Page 20: Leveling The Speedlane Pro During Installation
Leveling the Speedlane Pro during installation: The Speedlane Pro includes an electronic level gauge that can be read via the provided software. This should be used to level the Speedlane Pro parallel to the road surface during installation on the pole. This will allow proper pointing adjusting using the camera. -
Page 21: Hookup
Hookup: Power Input: The Speedlane Pro radar features wide operating input voltage range of 9VDC to28V (48VDC PoE is an option). In a typical application it may be powered from a nominal 12V DC source and will feature best in class operational power consumption of 0.85Watts (please see Speedlane Pro SPECIFICATIONS for details). -
Page 22: Serial Connection
You may alternatively power the Speedlane Pro via “Power Over Ethernet” (PoE) option. This option must be purchased when ordering the Speedlane Pro from the factory and is an additional feature to the Ethernet option. Please note that since the Speedlane Pro uses only 4 wires for Ethernet, you must use the “power over data pairs”... -

Speedlane Pro Target Verification and Lane Setup STEP #3: Check target signal strength and location on the real time range plot. After initializing the background clutter map in the SPEEDLANE Setup Tab, click on the “SPEEDLANE Plot” tab. This will bring up a real time “chart recorder” type plot of tracked targets as shown below. - Page 32 Check Target Signal Strength: Excellent return signal strength from these vehicles on the road. Check “Show RSS” to show the target Receive Signal Strength. 3 or more solid bars out of 5 represent a good signal. You should adjust the radar pointing to get 3 or more bars to the desired target(s).
