III A missile defense system must be able to deal with an attack containing decoys in addition to warheads. If the defense system does not have enough interceptors to shoot at all the incoming objects, it must be able to discriminate between decoys and warheads. This discrimination process is not perfect and results in two types of errors: leakage (not shooting at warheads) and false alarms (sh...

The United States Department of Defense (DoD) is engaged in a mission to unify its software systems towards a “net-centric” vision— where commanders gain advantage by rapidly producing, consuming, and sharing information using service oriented architectures (SOAs). In this paper, we study the cyber survivability of mission-critical net-centric systems, focusing on Ballistic-Missile-Defense (BMD...

EXECUTIVE SUMMARY This paper describes how an Enterprise infrastructure is supporting agility on two ARPA initiatives namely, RASSP (Rapid prototyping of Application Specific Signal Processors), and AM3 (Affordable Multi-Missile Manufacturing). The two programs involve several large enterprises linked electronically to form virtual enterprises and aiming to address the issues raised by the cons...

Multistatic radar systems can be used in many applications such as homeland security, anti-air defense, anti-missile defense, ship’s navigation and traffic control systems. Multistatic radars, which are capable of detecting and tracking flying objects in three-dimension coordinate systems, are simulated in this paper. The location and velocity of flying objects as well as their radar cross sect...

High-level networking model and technology suitable for effective management of large distributed dynamic air and missile defense systems will be described which can cope with different kinds of unpredictable and asymmetric situations including massive air and missile attacks. Using this Spatial Grasp Technology (SGT), intelligent distributed command and control infrastructures, as demonstrated...

uring June 1995 through September 1998, APL conducted a series of Warfare Analysis Laboratory Exercises (WALEXs) in support of the Naval Air Systems Command. The goal of these exercises was to examine a concept then known as the Air-Directed Surface-to-Air Missile (ADSAM) System in support of Navy Overland Cruise Missile Defense. A team of analysts and engineers from APL and elsewhere was assem...

In summer 2000, the Clinton administration is scheduled to decide whether to authorize deployment by the United States of a limited national missile defense (NMD) system. This date arose from a “3+3” policy announced in the midst of the 1996 election campaign: under it, the administration would conduct research and development on missile defenses until 2000, then decide whether to proceed to a ...

An important factor in the Joint Operation, interoperability is regarded as the key to win a battle. This study proposes a quantitative method to assess the system interoperability at architecture level based on DoDAF (Department of Defense Architecture Framework). The proposed method works by extracting the systems and their interoperability features from the DoDAF model and by referring to th...

This paper addresses the issue of predicting where a boosting threat missile will be several minutes in the future. The prediction issue is important for missile defense because it can be a key factor in determining how heavy an exoatmospheric interceptor has to be. Simplified examples are presented comparing the effectiveness of two prediction methods in terms of accuracy and robustness. Final...
