Today's highly capable threats, low reaction time scenarios, diverse sensor environments, and intelligent adversarial jamming capabilities require a fast and robust tracking fusion process. The fusion of all organic (belonging to the same platform, e.g., ship, airplane, submarine, ...) sensor tracking processes improves the operational effectiveness of any platform be it fire control or situational awareness. This article discusses two concepts relevant in many existing platforms: the fusion of sensors tracks, and the optimal use of legacy systems in the fusion process.

In this paper we are concerned with Design For Quality (DFQ), which has recently attracted much attention in system design. Our aim is to introduce effective methods for estimating the variability of a system's performance. The linear approximation method is perhaps the most often used method for predicting variance propagation in a system. In this paper, we exploit the Moment Method in statistical analysis to extend the linear approximation to quadratic approximation, which will be referred to as Quadratic Propagation of Variance (QPOV). The derivation of the new method is provided and some results of its application in a real circuit are given. Our examples indicate that the new method QPOV gives much more accurate estimates for performance variability. Also this method can be used in other CAD fields.
本文关注的是近年来系统设计中备受关注的面向质量的设计(DFQ)。我们的目的是介绍有效的方法来估计系统性能的可变性。线性逼近法可能是预测系统中方差传播最常用的方法。本文利用统计分析中的矩量法，将线性近似推广到二次近似，即二次方差传播(quadratic Propagation of Variance, QPOV)。给出了新方法的推导过程，并给出了在实际电路中的一些应用结果。我们的例子表明，新方法QPOV给出了更准确的性能可变性估计。该方法也可应用于其他CAD领域。

There are considered in present paper the general aspects of mathematical foundation of onboard pilot's control actions during maneuvering support system (PCASS) software and its implementation in tactical flight simulator for pilot's control actions during maneuvering skills training via shortcut-time spatial trajectories optimization and their visualization in the view of "road-in-the-sky" image for further tracking in direct with foresee regime or (semi) automatic mode. There are disclosed two specially designed for this purpose "fast" modifications of direct method of variational tasks solution-the first (for short-term trajectories with strong constrains on control functions) based on 5/sup th/-7/sup th/ power polynomials optimal trajectory approximation, the second (for long-term flight on a route trajectories) based on spline approximation. For long-distance guidance on the moveable object it's utilized several-steps approach based on mentioned 5/sup th/-7/sup th/ power polynomials optimization. Paper is attended with examples of designed software operation on seminatural advanced simulator of high maneuverable airplane with investigation prototype of PCASS.

Operational deficiencies exist in the current ability to perform high resolution synthetic aperture radar (SAR) targeting for precision strike missions in difficult electronic countermeasure (ECM) and anti-aircraft environments. Increasingly sophisticated enemy defenses require that fire control information be derived from highly maneuverable aircraft trajectories rather than traditional straight-and-level flight. In addition, target area, aspect information is needed to determine optimal attack approaches. These imaging and targeting conditions impose severe performance requirements on the sensor aircraft motion compensation system (MCS), and dictate the need for sophisticated algorithms to counteract ECM threats. This paper describes the development of a user friendly "Design Tool" for modeling and analysis of airborne radar system performance for SAR imaging and Precision SAR Targeting.

Stochastic temporal reasoning in situation assessment (SA) is very important in many applications. The approach based on Maximum Likelihood Estimation (MLE) treats the unknown temporal variable as a constant which doesn't use a priori information and generates a larger estimate variance. In this paper, the relation model of known temporal information and unknown temporal variable has been established which can also be used to MLE-based method. In the model, the forward and backward reasoning algorithm about time instants has been derived by treating the unknown temporal variable as random variable and introducing MAP estimation into temporal reasoning. The performance analysis between MAP-based method and MLE-based method shows that under some conditions, the estimate variance of MAP-based method is lower than MLE-based method, and we have given these conditions by experiments.

This study reviews the implementation and cost of implementation of sample F-15E job guide data in Standard Generalized Mark-Up language (SGML) format into five different interactive electronic technical manual (IETM) presentation systems. IETMs improve aircraft maintenance efficiency by allowing maintenance personnel to more easily locate needed information. Two of the presentation systems are classified as class (3), one is classified as a class (3)+ and two are classified as class (4) IETMs. This report provides detailed information on the compliance of each presentation with applicable military specifications and the effort and cost associated with implementing the sample data into each of the presentation systems. Specific conclusions are drawn concerning the various IETM systems. This study was performed by the Mercer Engineering Research Center (MERC) under contract to the United States Air Force, Warner Robins Air Logistics Center (WR-ALC).

A target identification algorithm can be thought of as being comprised of a pre-processor, discriminant generator, and a post-processor. The pre-processor forms and otherwise conditions the target signatures. The discriminant generator forms scalar quantities that represent the closeness-of-fit of each signature to the target classes of interest. Finally, the post-processor utilizes those scalars to form a decision as to the target that the signature came from; i.e., the identity of the target being examined. In this paper, we start with a full set of discriminants generated by a particular pre-processor and discriminant generator operating on high-range-resolution (HRR) signatures of aircraft, and we perform various experiments to determine the effect on algorithm performance of applying various post-processing techniques. The overall target identification algorithm is described, numerous post-processing techniques are introduced, and their effects on performance are tabulated. It is shown that optimal combined performance of these techniques does not necessarily follow from combining the individual best-performing techniques. That is, an optimal post-processing architecture cannot be derived from a simple search of the diagonal of the multi-dimensional set of post-processing options.

As defense budgets continue to shrink the Air Force needs an improved method for procurement of weapons electronics systems. We propose strengthening the front end to the procurement process by allowing the users to try out their ideas before committing to a lengthy and expensive procurement cycle. Modeling and Simulation (M&S) shows great promise as a tool to achieve cost effective and requirements focused procurement. Procurers need a simulatable model to allow their users to test a virtual version of their procurement specifications. This paper presents an example of using a VHDL model, documentation, and associated test vectors as a "procurement specification".

In this paper, we describe a tool developed under the DARPA/sup 1/ sponsorship in the Systems On Chip Created using Extended Requirements language (SOCCER) program to search and retrieve Intellectual Property (IF) for reuse in a mixed-signal electronic system design. Given system requirements specified formally as preconditions, postconditions, and constraints, the tool searches a database of component specifications for existing IP and then provides a list of IP components that completely or partially match the system specification as output. The system requirements are specified using an extended VSPEC, a formal interface specification language developed to specify digital systems under the sponsorship of the Air Force in the CEENSS program and then later extended under the SOCCER program to specify analog and mixed-signal systems as VSPEC-AMS. In addition, the SOCCER tool employs an extended REBOUND, a search and retrieval tool originally developed under the DARPA RASSP program and then extended for analog and mixed-signal systems under the SOCCER program. In this paper, we provide a tool overview and vision, describe its background present extensions developed under the SOCCER program and then illustrate the workings of the tool with an example. SOCCER is a Phase I STIR program that began in June of 1997 and has established the proof-of-concept for the tool described above. In addition, SOCCER has the potential to leverage the AF sponsored VHDL-AMS Synthesis Environment (VASE) program to go from concept (system requirements) to implementation (VHDL-AIMS behavior which could be synthesized using the VASE tool under development).

Complex simulation-based design efforts suffer from lengthy simulations. It becomes difficult to develop and debug hardware models when the turn around time between development and test results are measured in terms of days or even weeks. A significant lag between development and architecture performance test results cast severely hamper the design effort. A strategy for accurate rapid modeling of a complex digital design is presented The precision of a cycle accurate hardware description language (HDL) model was combined with the speed of software modeling to provide rapid system performance evaluation. The hardware model was used to generate timing information and resource requirements from a limited data set. These results were back annotated into the existing algorithm written in a high-level programming language, in order to generate realistic, full system, performance parameters and thus quickly assess the satisfaction of performance constraints by the chosen architecture.
