The Common IED Exploitation Target Set (CIEDETS) ontology provides a comprehensive semantic data model for
capturing knowledge about sensors, platforms, missions, environments, and other aspects of systems under test. The
ontology also includes representative IEDs; modeled as explosives, camouflage, concealment objects, and other
background objects, which comprise an overall threat scene. The ontology is represented using the Web Ontology
Language and the SPARQL Protocol and RDF Query Language, which ensures portability of the acquired knowledge
base across applications. The resulting knowledge base is a component of the CIEDETS application, which is intended
to support the end user sensor test and evaluation community. CIEDETS associates a system under test to a subset of
cataloged threats based on the probability that the system will detect the threat. The associations between systems under
test, threats, and the detection probabilities are established based on a hybrid reasoning strategy, which applies a
combination of heuristics and simplified modeling techniques. Besides supporting the CIEDETS application, which is
focused on efficient and consistent system testing, the ontology can be leveraged in a myriad of other applications,
including serving as a knowledge source for mission planning tools.
The US military has recently taken tactical steps to increase its ISR capabilities to support military operations. Due to
the dynamic capabilities of the terrorist threat, there is a need for a payload- and airframe-agnostic, rapid-deployment
sensor system that can be used on multiple airframes for in-theater missions and for the test and evaluation of sensors
prior to fielding. This "plug-and-play" system, based upon the Oculus Sensor Deployment System technology, uses a
system-of-systems approach to modularize the base platform, thereby allowing the system to conform to aircraft such as
the C-130, C-27, V-22, CH-47, CH-53 and CASA-235 without any modification to the airframe itself. This type of
system can be used as (1) a versatile, cost-effective test and evaluation platform for current and developmental sensors as
well as (2) an in-theater ISR asset that can be used on readily available airframes at a particular location.
This paper illustrates the CONUS and OCONUS mission potential of this multi-airframe system and outlines the novel
design characteristics that the Airframe Agnostic Roll-on/Roll-off (AA-RORO) sensor platform incorporates to make it
the most versatile, rapid-deployment sensor platform available to support near-term U.S. military operations. The
system concept was developed with the support of and input from multiple military agencies and the respective branches
they represent.
