8. INFLUENCES AND INTERFERENCE
Interferences from external sources may affect the standard
operation of any radar device, including the Talon. These
influences can be natural or man-made, however the Digital
Signal Processing circuitry will eliminate most of these
influences and a knowledgeable operator should be able to
determine the nature of the influences and their effect, if
any, on the performance of the Talon.
8.0 NATURAL INFLUENCES
1. Heavy rain and blowing dust can cause a scattering
effect which may reduce the effective range of the
Talon. The patrol speed can also be affected by driving
rain. It is recommended that the operator compare the
patrol speed reading and the speedometer reading
frequently during rainy periods.
2. Terrain can affect the range of the Talon. Improper
aiming of the antenna can cause the radar to appear to
have short range. If the target vehicle were on a slight
incline, the antenna could be shooting short of the
intended target vehicle.
3. Strong reflections from roadside objects, such as large
signs, parked cars and buildings can cause double
bounce reflections which are the same as the patrol
speed. These “harmonics” are detected by the DSP,
which inhibits their display.
The TARGET window will display “- -“ until this
condition no longer exists.
