Maritime security poses daunting challenges of protecting thousands of potential targets, fixed and mobile, dispersed across US coasts and waterways. We describe an integrated approach to systematically assessing risks and prospective strategies for mitigating those risks. The maritime security risk analysis model (MSRAM) quantifies maritime risk in terms of threats, vulnerabilities, and consequences. We are extending MSRAM with novel "what-if" behavioral simulation software that projects the likely reduction of risks over time from adopting strategies for allocating existing security assets and investing in new security capabilities. Projected outcomes (and costs) can then be compared to identify the most robust strategies for mitigating risk. This decision support method can be re-applied over time as strategies are executed, to re-validate and adjust them in response to changing conditions and terrorist behaviors. This dynamic portfolio-based approach improves confidence, consistency, and quality of risk management decisions. It is extensible beyond the maritime domain to address other critical risk areas in homeland security.

Accurate, periodic calibration is required to operate IMS, GC, and portal security systems with maximum efficiency, surety, and operator confidence. To this end, we are presently developing a microfabricated device for on-demand calibration of fieldable contraband detection instruments. Using robotically-assisted picoliter dispensing methods, precise nanogram or larger amounts of calibration compound(s) are placed on micron-sized bridge structures. Resistively heating these structures delivers precisely quantified low-levels of calibration compounds to the detector systems. This provides reliable calibration for identification and quantification of explosives, narcotics, and other contraband.

The inability to seamlessly merge technologies on a flexible, versatile platform has severely limited the development of a truly integrated checkpoint screening system that can effectively detect all explosives and other threats while maintaining throughput demands. L-3 Security and Detection Systems, Inc. is developing a fully integrated checkpoint security solution that answers this challenge with stable, blended, state-of-the-art inspection technologies that dramatically increase the probability of threat detection. The system provides state-of-the-art technology integrated under one umbrella. Fused sensor data and "plug and play" elements combine to allow maximum user flexibility in meeting both customer and regulator checkpoint objectives.

A signature-based radiation technique for detecting chemical explosive is described. Radiation techniques offer the advantage that they can operate at standoff, although rapid detection of explosives at safe standoff distances remains problematic. The technique we describe differs from the major nuclear approaches, which involve imaging (using either photon or neutron interrogation) and/or quantitative analysis (for instance by use of prompt-and inelastic-scatter gamma-ray production based on neutron interrogation). Our technique utilizes both photon and neutron interrogation but avoids imaging or quantitative analysis. The technique, which we call signature-based radiation scanning (SBRS), limits itself to detecting whether a target contains an explosive and does not attempt to characterize the internals of a target further. A template-matching technique is employed, which provides a single figure-of-merit whose value is used to distinguish between safe targets and those containing explosives. Both simulation and experiment have been used to verify the validity of SBRS.

Over the course of the past year, millimeter wave-based (MMW) imaging systems have entered the market, been deployed, and been evaluated in various trial applications. The attractiveness of millimeter wave solutions is that they combine an excellent combination of technology maturity, low cost commercialization, and important performance attributes. These characteristics make them uniquely suited for many important types of concealed weapons and contraband threats, supporting a volume of potential applications. This paper will discuss the state of MMW imaging and likely forward trends.

Structural health monitoring is desirable in many fields to provide a means of damage detection on a variety of structures. Unfortunately, the ability to equip structures with health monitoring systems is limited by the development of adequate hardware. Previously, prototypes using the impedance-based health monitoring method have been developed to lay a foundation for permanent structural damage detection. These prototypes served their purposes, but has shortcomings such that large size and high power consumption. In this paper, all-digital excitation and sensing techniques are developed to reduce both the size and power dissipation. The digital techniques are implemented onto a new prototype, which achieves substantial reduction in size and power consumption. Validation of the new hardware on a representative structure is presented and compared with traditional techniques for structural health monitoring.

The Department of Homeland Security is sponsoring development of standards for urban search and rescue (USAR) robots. This program is being coordinated by the National Institute of Standards and Technology and will result in consensus standards developed through ASTM International. Robot deployment categories and performance requirements have been identified by emergency responders, These requirements are being translated into tests and metrics with which to measure the performance of robots. Several test methods have been entered into the standards process. Three major exercises have been held at US&R training facilities, in which responders work side-by-side with robot manufacturers to experiment with robot deployments in relevant scenarios and to refine and expand performance requirements. To date, over forty robots, including ground, aerial, and aquatic, have been involved. Supporting projects are developing an ontology of robot capabilities and situational constraints. In general, these efforts will enable responders to enhance their effectiveness while reducing risk to personnel during disasters through use of robotic assets.

In addition to the speaker and the microphone, the radio handset contains the baseband electronics for a digital radio. This includes an Ethernet jack, a full network protocol stack, an OFDM baseband modem and a user interface to place calls: one-to-one (private line) or one-to-many (talk groups). The handset plugs into an ordinary land mobile radio that is used only for up conversion to RF and power amplification. No modification to the radio is needed. Using existing radios means the existing infrastructure and existing channel frequencies are also used. This is a significant cost savings to achieve interoperability, and it immediately puts the technology into the marketplace. A distributed digital radio (DDR) is a 6-way radio: voice/RF, voice/Ethernet and Ethernet/RF. In computer network terminology, a DDR is a hybrid router - hybrid is used because the PHY layer at each of the ports is different: audio, RF or Ethernet. A public safety radio network with DDRs becomes a wireless local area network (WLAN). The WLAN is not WiFi; it is a client mesh with an Ethernet backplane. The DDR provides 2G communications and cost effective IP-based interoperability to all first responders - even to the local and rural public safety agencies with conventional analog radio networks. This paper discusses WLAN interoperability architectures, and it traces the development of the DDR.

The protection of critical infrastructure is a growing concern within the transportation industry. Raytheon is developing a system architecture and design for a perimeter security system that specifically addresses this issue for large facilities such as airports, seaports and rail facilities. The architecture uses the DoD's Architecture Framework guidelines. It employs a multi-sensor approach, including ground surveillance radars and cameras, to detect, assess and track perimeter incursions. It is designed to operate 24/7 in all weather conditions. A command and control center provides timely and accurate situational awareness to facility security personnel responsible for monitoring and managing incidents. Mobile communications also provide situational awareness to first responders in the field. The architecture supports integration with existing security systems, such as access control and closed circuit television, to centralize security monitoring for the entire facility. This architecture is the basis for the Port Authority of New York and New Jersey's Perimeter Intrusion Detection System for four airports, including John F. Kennedy International. Raytheon's system engineering process as applied to the perimeter security application is described, with focus on the key early process phases of threat analysis, operational concept generation, system requirements analysis, and system architecture and design development. Key technical parameters, including probability of detection and nuisance alarm rate, that drive the system design and cost are also discussed. Raytheon has found that the quality of the system engineering effort directly determines the quality of the resulting system and its ability to satisfy the customer's mission needs.
