The GCA/PAR-2000 is a compact Airport
Surveillance Radar (ASR) / Precision Approach
Radar (PAR) System providing high performance
target detection in the airspace around an
airport or air base. Simultaneous ASR and PAR
operations from the single sensor provide
accurate display of both types of radar data.
Versatile,
multimode, digital color displays and full
communications support all controller
operations. The ASR covers 30 nautical miles (nmi)
at altitudes up to 8,000 feet. The PAR coverage
is up to 20 nmi with azimuth coverage of 30
degrees and elevation coverage of 8 degrees. A
PAR-only version (PAR-2000) is also available.
The GCA/PAR-2000 comes in fixed, transportable,
and mobile (AN/MPN-25) versions.
Superior Operational and Technical Performance
The GCA/PAR-2000 is fast and easy to install;
its human-machine interface is full color and
carefully arranged to reduce fatigue in the
high-stress controller environment; and runway
changes are achieved in less than a minute –
much faster than any competing system. The GCA/PAR-2000
achieves excellent
target detection and tracking even in severe
environments such as heavy rain or snow.
High stability and advanced digital processing
including Moving Target Detection (MTD) and
mapping ensure adaptation to the changing
environment.
Versatile High-Resolution Multimode Displays
The GCA/PAR-2000 includes two or more universal
displays that controllers can individually
assign to the ASR or PAR mode based on traffic
needs. The FAA-certified ASR display format
covers the air situation. The PAR display
provides the 3-D landing situation in a
state-of-the-art digital Az-El format. This
patented display adds an innovative “bullseye”
for a pilot’s view of the approach.
Focused Advanced Technology
The GCA/PAR-2000 achieves its outstanding
capabilities through integration of advanced
technology into a cohesive user-friendly system.
Air cooled GaAs Transmit/Receive Modules
populate two active apertures for the azimuth
and elevation antennas, thereby eliminating the
single-point transmitter failure. Commercial
off-the-shelf (COTS) processors and power
supplies ensure low-cost and high reliability
implementations.
Non-stop Operation and Low Support Cost
The GCA/PAR-2000 modular, open architecture and
solid-state design achieves availability and
reliability superior to any other radar-based
landing system. Incorporated redundancies
provide fail-soft protection. Very low support
costs are inherent through highly reliable
solid-state technology, minimized unique Line
Replaceable Units (LRUs), and extensive built-in
test. Reduced deployed maintenance costs are a
direct result of designed-in fail-safe/fail-soft
operation requiring only scheduled periodic
maintenance. Maintenance is further enhanced
through the optional capability to remotely
monitor all system functions via telephone
lines.
