TMT-6F photo radar

Traffic Monitoring Technologies (TMT)
Swiss-made (Multanova 6F) modular across the road photo radar

• attended (operator) and unattended (no operator) use
  Instant On feature (operator controlled)
• across the road radar (see figure below)
  22 degree horizontal angle (with traffic direction)
  -7.5 degree vertical angel (pointed down 7.5 degrees)
• multi-unit Ka band radar (34.3 GHz +/-100 MHz)
  -- antenna
  -- central control unit
  -- remote control with speed display
  -- still camera (optional flash)
  usually mounted in the back of a truck, van, station wagon, or trailer.
  Often hidden from traffic (mounted to a vehicle that appears disabled).
• measures on-coming traffic only
• stationary mode only
• speed measuring range: 15 to 155 mph
• records violations with a photograph (includes speed, date, and time)
• Specifications

        ACCURACY   +/- 1 mph (up to 100 mph)
                   +/- 1 percent (over 100 mph)
                  (+/- 1.6 mph for 155 mph target)

 MEASURING RANGE   15 to 155 mph

       FREQUENCY   34.3 GHz +/-100 MHz (Ka band)
  TRANSMIT POWER   0.5 mW (maximum)

         ANTENNA   parabolic reflector
       beamwidth   5 degrees horizontal
                   5 degrees vertical
       side lobe   -20 dB or better

           POWER   lead storage battery
                   12 Vdc (3.0 A max, 2.2 A typ)

ELECTRONIC FLASH   only on vehicle mounted systems
                   2 settings
                   170 watts flash energy (0.9 sec recharge time)
                   340 watts flash energy (1.8 sec recharge time)
PHYSICAL
         ANTENNA   5 x 8 in   
           depth   13.8 in  
          weight   4.5 lb

  OPERATING UNIT   3.75 x 7.0 x 2.25 inches
          weight   1.75 lb

 CENTRAL CONTROL   12.5 x 11.0 x 4.25 inches
          weight   9.25 lb

The beam footprint (beam intersection of ground) depends on antenna height (above ground), vertical pointing angle (-7.5 degrees), horizontal pointing angle (22.5 degrees), vertical beamwidth (5 degrees) and horizontal beamwidth (5 degrees). Radar effective operating range is about 150 feet.
