Default COBRA BRASS family of sensors

For some years, there have been various discussions about the COBRA
BRASS sensor,
http://www.fas.org/spp/military/prog...cobrabrass.htm

It's been thought/speculated that, in addition to the one that
apparently went up on the NRO's CAPRICORN satellite in January 1998,
there were others, probably on the Titan Launch Dispensers that
carried the Navy's NOSS-2 triads into orbit and then went into MEO.

It turns out that the Naval Postgraduate School site has some items
that pretty clearly establish that COBRA BRASS is a series of
sensors and imply a bit about what it does.

COBRA BRASS FOR BATTLESPACE CHARACTERIZATION AND BATTLE DAMAGE
ASSESSMENT (U)

William Mitchell Darling-Lieutenant, United States Navy
B.S., Purdue University, 1986
Master of Science in Systems Technology - March 1997

Advisor: Dan C. Boger, Command, Control, and Communications
Academic Group

Second Reader: Kyle T. Alfriend, Navy Tactical Exploitation of
National Capabilities (TENCAP) Chair

Battlespace characterization and battle damage assessment are
important to the warfighter and must be a part of the strike
planning. The Cobra Brass research and development sensor has
the capability to provide information the warfighter canuse to
aid in his decision making. Navy TENCAP is using Cobra Brass
in an operational mode to test the feasibility of operationally
tasking this type of sensor. This thesis educates the warfighter
on the Cobra Brass family of sensors, investigates the utility
of Cobra Brass for battlespace characterization and battle damage
assessment, and develops a concept of operations for the non-
imaging infrared sensors presently deployed and for future such
sensors.

CENTRAL MASINT ORGANIZATION R&D TECHNICAL ASSISTANCE
R. Chris Olsen, Associate Professor
Department of Physics
Sponsor: Defense Intelligence Agency

OBJECTIVE: The proposed effort is to support the Central MASINT
organization in its research and development efforts, particularly
in the area of spectral imagery and high frame rate non-imaging
infrared systems. Technical development of the Cobra Brass F
System, exploitation of Cobra Brass F data and development of a
UV spectral imager are supported.

SUMMARY: Significant progress was made with the Cobra Brass studies,
including work in target tracking and aerosol discrimination. Work
on a new UV spectrometer was begun. A two-day workshop was held on
the problem of detecting chemical and biological agents.

DoD KEY TECHNOLOGY AREAS: Other (Remote Sensing)

KEYWORDS: Environmental Monitoring, Remote Sensing

in the area of Spectral imagery and high frame rate non-imaging
infrared systems. Technical development of the Cobra Brass F System,
exploration of Cobra Brass E data and development of a UV Spectral
imager are supported.

SUMMARY: Significant progress was made with the Cobra Brass studies,
including work in target tracking and aerosol discrimination. Work
on a new UV spectrometer has begun.

VOLCANIC ASH DRIFT
Richard C. Olsen, Associate Professor
Department of Phyics
Sponsors: U.S. Geological Survey and Naval Postgraduate School

OBJECTIVE: The proposal is to enhance model based ash drift forecasts
using near real time observations. Products derived from classified
and unclassified systems will be used to provide model input.
Campaign strategies will be developed for acquisition of necessary
"ground truth" information.

SUMMARY: Volcanic ash clouds are a hazard for civil and military
aircraft. The ability to identify boundaries of hazardous regions
requires both observations and models of ash cloud behavior. In
the first year of study, data from the AVHRR sensor were acquired
for volcanic events on the Kamchatka peninsula. Software was
developed for the analyis of such data in order to distinguish
between ash and water clouds. These data were compared with
observations from national systems, which showed agreement at
some times, but "false alarms" at others. The Cobra Brass sensor
launched in late 1997 will provide a complementary data set which
should enable real-time warnings and model input. Analysis of Cobra
Brass data will begin in 1998.

It appears that Cobra Brass E was the sensor on the NRO
CAPRICORN/USA 137 satellite launched on 29 January 1998
(http://www.astronautix.com/craft/capicorn.htm)

Note that the inferred existence of CB A,B,C and D is
consistent with the speculation that they are carried
on the NOSS-2 A/TLD/SLDCOM hosts (three in orbit, one lost
in a launch accident).
