INTRODUCTION
S
PATROL
is a K-Band speed-measuring radar that can be mounted in a variety of ways, and is operational with
one or two antennas. Utilizing a state-of-the-art Digital Signal Processor (DSP), S
PATROL
provides a level of
performance, convenience, and accuracy previously unavailable. The DSP performs the critical filtering and timing
functions required for speed measurement in its software, as opposed to its hardware. This provides less unit-to-unit
variation, more reliable performance, and easier maintenance. The unique feature of the S
functions required for speed measurement in its software, as opposed to its hardware. This provides less unit-to-unit
variation, more reliable performance, and easier maintenance. The unique feature of the S
PATROL
is that it can be
upgraded in the future by simply reprogramming the flash memory chip, preventing obsolescence!
S
PATROL
operates in K-Band (24.15 GHz) and provides a hold mode. Both K-Band operation and the hold
feature reduce the possibility of detection by radar detectors. Target-speed locking, Track-thru-Lock speed, Faster Speed
Tracking, and the Doppler audio capability assist the operator in positive target identification and provide operating
convenience.

INSTALLATION
S
PATROL
consists of a counting unit with integrated display; one or two antenna units; and a wireless/wired
remote control unit. S
PATROL
is powered from the 12-volt vehicle power system using a Power Cable from the
counting unit. Each system component should be installed in a location that provides good operator visibility and
convenience, but does not obscure the road or interfere with air bag operation. The K-Band antenna units are fully
waterproof and can be installed outside the vehicle, if desired. The counting unit with display, and remotes are not
waterproof and must be installed in a location sheltered from the weather. Longer cables are available from the factory for
specific installations, if needed.

Display/Counting Unit -
To mount the counting unit, connect the Power Cable to the power jack on the back of the
counting unit. Plug the front and/or rear antenna cables into the back of the counting unit. If using only one antenna, plug
it into the front jack. After attaching the mounting bracket to the selected mounting surface with Velcro or screws, insert
the combined display/counting unit into the mount and secure with thumbscrews (provided) into the threaded holes located
on each side of the counting unit.

Antenna Unit -
The radar can consist of either one or two K-Band antennas. Before proceeding with the final
installation, check the intended mounting locations for fan interference on both antennas. See the section on fan
interference, page 17. Find a suitable location and attach the antenna mounting bracket to the selected mounting surface.
Attach the antenna unit to the bracket. Connect the antenna cable to the antenna. Repeat these steps for the second
antenna, if desired.

Cordless Ergonomic Remote Control -
The only installation required for the ergonomic remote control is to install
the 3V Lithium battery (type 123). Remove the battery compartment cover by pressing down on the battery cover latch
and rotating the battery cover away from the case. Install the battery, paying attention to the polarity markings. Replace
the battery cover until it snaps in place. Velcro may be applied to the back of the remote control unit to attach it to the dash
or other locations. Also, a microphone lug (supplied) can be attached to the back of the ergonomic remote control to allow
installation into a microphone holder. An optional lanyard is also available. This remote control can be used in a wired
mode. The Remote Control can be operated in wired mode by connecting a standard RJ-11 modular telephone handset cord
(P.N. 155-2213-00 or Radio Shack #279-312). The cord is connected to the remote and radar unit, and battery removed for
wired operation.

THEORY OF OPERATION
Stationary Mode -
S
PATROL
uses the Doppler frequency shift technique to measure the speed of moving
vehicles. This technique is based on the Doppler Theory, which states that a radar signal reflected from a moving target
will experience a frequency shift that is proportional to the speed of the target relative to the radar. Circuitry in S
will experience a frequency shift that is proportional to the speed of the target relative to the radar. Circuitry in S
PATROL
processes the reflected signal to obtain the frequency shift. The Digital Signal Processor (DSP) then measures the
frequency shift to obtain the target speed. In stationary mode, the transmitted signal strikes a moving target and is reflected
back to the antenna. S
back to the antenna. S
PATROL
processes the signal to obtain the target speed. Targets, both approaching and
receding, generate the same Doppler frequency shift; therefore, targets traveling both directions can be measured.
Opposite Lane Moving Mode -
In opposite lane moving mode, two (2) signals must be processed to determine target
speed. The first signal, patrol speed, results from the radar signal reflecting from passing stationary objects. Since the
