There has been considerable interest in applying sensor array signal processing techniques to a variety of radar applications. The use of adaptive spatial and temporal filtering techniques has been widely discussed. The relative expense of building hardware and conducting experiments has led to a strong emphasis on simulation as a way of developing new equipment, but there are currently no software tools available that are particularly suited to the problems of simulating sensor array systems. This paper describes the current state of development of an adaptive array processing toolset (AdAPT), which is capable of modelling systems comprising large numbers of sensors. AdAPT encompasses modelling a target environment, design of array hardware, application and design of signal processing algorithms and the display and interaction of data as it flows through the design scenario. We also discuss the graphical user interface to AdAPT.

For many novice users the interface to Matlab can appear somewhat daunting. users brought up on programs with a graphical user interface can find the command line interface presented by Matlab daunting. For average users, requiring the ability to perform tasks such as Control System design and basic Signal Processing operations, numerous calls to Matlab routines need to be learnt to achieve even the simplest of results. In order to alleviate this obstacle and provide an easy to use and intuitive interface a graphical 'front end' employing the freely available Tcl/Tk programming toolkit is utilised to provide a point and click and drag and drop interface in order to enable rapid design and prototyping with minimal knowledge of the underlying computer engine, in this case Matlab.

Submarines detect other vessels with a variety of different sensors, each of which produces a range of output data types. To enable the data to be correctly understood, the various sensor outputs must be collated together to form a single representation of each detected vessel. Data fusion describes the collection of analysis and combination processes, used to collate the sensor data. There are a considerable number of techniques and algorithms available to perform data fusion, the limitation is, however, not the technology, but the ability to use the correct technology to build an operable system that solves the correct problem. The approach taken in this paper is to specify the data fusion problem in isolation from the selection of implementation technology. As one of the technologies is the human operator, this approach encompasses the partition of tasks between the man and the machine, from which a specification of the MMI emerges. Within this paper, a development method is described, which is followed by an example of a submarine data fusion system.< >

Reusing software architecture, which is a kind of coarse-grained software resources at design time, is always a very difficult problem in the realm of software engineer. We consider that there are two fundamental reasons for this problem: one is the lack of information which supports the process of reusing software architecture; another is the lack of effective reusing approach. So this paper proposes RIM4RSA - reflective information model for reusing software architecture supporting the reuse of architectural level design, which offers the information support for reusing software architecture and its constituents at design time by modeling the meta-information about the base-level to construct a meta-level. Moreover, this paper illustrates the approach to construct meta-level and base-level of the RIM4RSA, and presents the implementation solution of RIM4RSA. At the same time, we put forward an approach for reusing software architecture based on the use of RIM4RSA.
