Efficient Deployment Minimal Crew
In its ground based configuration the Improved Sentinel radar
system consists of an Antenna Transceiver Group (ATG) and the
HMMWV based prime mover group (HVG). The system also
includes an integrated identification friend or foe (IFF) capability that
helps prevent fratricide. The Improved Sentinel is fully operational in
minutes. It can be emplaced in less than 15 minutes and march
ordered in less than 10 minutes by a two person crew. There is no
need for any additional special ground handling equipment or
personnel. Only a two person crew is required for full Sentinel
operation; one operator and one maintainer. The highly
transportable Improved Sentinel Radar meets todays force
structure reductions by maximizing system deployability and
survivability, while minimizing crew requirements.
Electronic Maintenance Manuals Ensure Accuracy
Improved Sentinels comprehensive Interactive Electronic Technical
Manuals (IETMs) ensure that end users have convenient access to
current data for on-site repairs. Maintenance manuals and
applicable schematics are easily accessed for quick and easy system
diagnostic and expeditious repair. Distributed on CD-ROMs, IETMs
can be run on any Windows-based laptop or desktop computer with
a standard CD drive. Updates, when necessary, are distributed
quickly to the field by providing a simple, revised CD-ROM that
includes all previous information as well as the latest
changes/improvements.
Sentinels Proven Performance
With more than 200 Sentinel radars deployed worldwide, military
forces have proven the reliability, maintainability, and availability of
the Sentinel in combat, key asset protection, high profile events and
training deployments. Sentinel demonstrations, tests, and worldwide
deployments with the U.S. Army and international armed forces have
confirmed the operational effectiveness of Sentinel against all air
threats. Sentinels AN/MPQ-64F1 configuration improves upon the
standard configuration and greatly enhances the radars capabilities.

AN/MPQ-64F1 Improved Sentinel
Protecting
the
Warfighter
from todays
advanced
airborne
threats Description:
The Improved Sentinel System
The world leader in dependable, easily maintained, highly mobile tactical air defense radar, the AN/MPQ-64F1 Improved Sentinel is a state
of the art, three-dimensional, phased-array system that operates in the X-band frequency range. More than 20 years of engineering
research, development, and implementation of modern radar and software technology have enhanced the quality of the Improved Sentinel
Radar system.
Its primary mission is to automatically detect, track, identify, and report airborne threats, including helicopters, high speed attack aircraft,
cruise missiles and unmanned aerial vehicles (UAVs). The Improved Sentinel is the standard for the alerting and cueing of targets to support
a variety of weapons, including Stinger missile based SHORAD weapon systems, VSHORAD missile systems and air defense guns. This
advanced tactical radar detects and tracks threat aircraft at several times the range of short-range weapons, providing early warning to
ground crews and supporting maximum-range engagement of threats. The Sentinels extended acquisition range is optimally suited for
medium range engagements with missile systems such as HAWK and Beyond Visual Range Engagements (BVRE) with Surface Launched
Advanced Medium Range Air to Air Missile (SL-AMRAAM).
Sentinel System Components
Todays evolving threats have created the need for a longer range, extremely mobile and highly accurate 3D radar to alert and cue todays
most advance Air Defense weapon systems. The Improved Sentinel provides the unmatched capability to exceed these requirements. The
Improved Sentinel is equipped with new, modern COTS based electronics which ensures greater performance while implementing a low risk
technology insertion. The Improved Sentinel Radar completed its initial fielding to the U.S. Military in April of 2006 and is now deployed
worldwide.
The Improved Sentinel Radar boasts an unmatched range extension improvement. Every major component of the radar is new and has
undergone numerous hours of testing, verification and validation of its unparalleled extended range threat detection. Incorporation of the new
components has resulted in a significant increase in early detection of cruise missiles, UAVs, Rotary Wing and Fixed Wing aircraft. This
improvement also enhances the radars capability to identify and respond to targets well beyond visual range.
The new signal data processor of the Improved Sentinel has multiple On-Board Computers and is upgraded
with a 10 slot VME-64x rack. Incorporation of the latest COTS technology brings improved A/D processing,
faster radar control processing and additional slot availability for future growth of the radar.
The Improved Sentinel also includes a new Exciter and Receiver. The Exciter is an X-Band, Single Lowest
Replaceable Unit (LRU) that utilizes a single master oscillator to generate frequency. This provides the
benefit of lower noise that allows for improved detection in Clutter. The radars Receiver is a Single Channel,
X-Band Frequency, Single LRU which is designed to work in concert with the new Exciter.
The X-Band Transmitter is modular and scalable from two to four TWT based Power Amplifiers for increased
radar range and reliability.
The New DC Motor Controller has a new digital interface to the Signal Data Processor which provides
selectable operator control of antenna direction and speed.

Receiver Elevated Sentinel and Tower/Platform Configurations
No other air defense radar is as versatile and adaptable as the Improved Sentinel Radar.
It is readily available in an aerostat borne configuration, easily adaptable onto towers and
platforms, in addition to its standard ground based tactical configuration. In the Elevated
Sentinel configuration, the radar has been repackaged in a lightweight, highly effective
system mounted to a 38 meter Aerostat, capable of extended deployments of up to 14
days of continuous operation. The Elevated Sentinel is ideally suited for extended range
coverage of ~150km for air defense, early warning and/or air surveillance missions.
The Improved Sentinel can be mounted onto elevated platforms at any height. It can be
placed on a platform in its trailer mounted configuration or palletized and hard mounted
directly onto the platform itself. It can also be mounted inside a radome if desired.
No other single radar provides this level of adaptability and versatility to meet the unique
needs/requirements of the customer.
The Improved Sentinel is unsurpassed in mobility. The uniquely compact, lightweight configuration of the
Improved Sentinel and its adaptable base allows the user a larger variety of inventoried vehicles that can
either tow or carry the radar. This is critical in times of limited vehicle availability.
Countering Low Flying Threats
For securing urban or isolated sites from covert aerial threats, the Improved Sentinel Radar is second
to none. The radar has proven experience protecting critical assets, key infrastructure and high profile
events from airborne threats flying below the horizon of conventional long range air defense radars. The
highly mobile Improved Sentinel Radar delivers accurate low-altitude surveillance of small to large
airborne objects, including cruise missiles, domestic and military aircraft, UAVs, helicopters
