SECTION 8 - INFLUENCES AND INTERFERENCE
8.4
8.2 GROUNDSPEED
True groundspeed of the patrol vehicle is required by all
moving traffic radar systems before a target vehicle’s speed
can be accurately computed. If the Falcon HR loses correct
groundspeed, the operator can recapture groundspeed by
quickly activating and then deactivating the HOLD mode.
If the speedometer input is being used with the Falcon HR,
the DSP will accurately track even a weak patrol speed
return due to the small tracking window, unlike radar
without speedometer input.
The Falcon HR will always look for and display
groundspeed before displaying any targets. The
groundspeed radar signature is unlike most target or
interference signals. The DSP can identify this pattern,
which is helpful in situations such as shadowing or
combined speeds. While the speedometer input and DSP
technology will eliminate most of the influences found in
moving radar, it is still the responsibility of the operator to
complete a tracking history on the target vehicle and verify
the patrol speed with the patrol vehicle’s speedometer.
Close observation of the patrol vehicle’s speed reading is
recommended to avoid possible confusion.
NOTE: The Falcon HR will not display patrol speeds
below 16 km/h, or below the patrol minimum
setting if the speedometer input is not used.
Operating moving radar in the rain and snow requires the
operator to pay close attention to the patrol speed. Since
rain, fog and snow may affect the ability of the radar
system to find groundspeed, the operator must verify the
displayed patrol speed reading is correct.
