Smart Patrol Search

As stated in section 7.6 the Golden Eagle II can be operated
with or without speedometer input. If the speedometer
input is not connected, the unit will use patent pending
Smart Patrol Search (SPS) software routines. This software
reduces patrol shadowing and patrol combining when
coming out of Hold mode by knowledge of how traffic
radar is typically used by the operator.
When using traffic radar in moving mode, typically the
operator will activate and deactivate the antenna transmitter
as needed to check the speed of target vehicles. The radar
may have been in Hold anywhere from several seconds to
several minutes. Each time the operator switches from
Hold to active mode, the unit must first capture the patrol
vehicle speed before any target speeds are processed. It is
this initial capturing from Hold that radar processing is the
most vulnerable to patrol shadowing or combining.
SPS software works by storing the patrol speed when the
operator enters the Hold mode. This has two purposes; 1)
to help track and/or 2) reject patrol signals when returning
to active mode. If the unit is in the Hold mode for a typical
amount of time (more than one second), the patrol will be
searched first in a region around the stored patrol speed.
Example: If the patrol vehicle is traveling 65 MPH and the
operator enters Hold mode, when the operator comes out of
Hold sometime later, the SPS software will search the
region around 65 MPH first for the patrol signal. If a 20
MPH shadowing signal was present, it will not be displayed
as a false patrol.
If, on the other hand, the unit is not in Hold for the typical
amount of time (less than one second), the region around
the saved patrol will be excluded from the initial patrol
search. Example: The patrol vehicle is traveling 25 MPH,
there is a strong approaching target traveling 45 MPH, and
the radar has mistakenly combined the two and is
displaying 70 MPH for patrol. The operator can quickly go
