Section 8—Influences and Interference

8.1 MAN-MADE INFLUENCES

1. Radar units may display incorrect speed readings from
various sources. These include shadowing, combined
speeds, moving cosine and fan interferences (splitting
speeds).
Unlike other radar, the DSP processor in the Talon can
sense and eliminate most of the interferences that other
radar might see as speeds during normal operation.
2. Patrol speed shadowing may occur when the radar unit
receives a stronger signal from a large vehicle traveling
the same direction than the groundspeed return signal of
the patrol vehicle. This difference speed may be placed
in the PATROL window and used instead of the proper
patrol speed. See 8.2 below.
3. The combined speed effect can occur when the patrol
vehicle and the target vehicle are approaching each
other at low speeds, usually in the 25 to 35 mph (40 to
56 km/h) range each, and at relative short distances,
usually less than 300 feet. The radar unit sees a strong
reflection from the combined speed signal and analog
radar units may display this speed instead of the true
patrol speed. The Talon with speedometer input will
eliminate this effect, and the unit will display the proper
patrol and target speeds.
4. The Talon has an onboard battery monitor to alert the
operator when internal voltage nears the minimum
operating voltage. See Sec. 7.1.1 for details.
