AdAPT-a toolkit for adaptive array signal processing

In recent years there has been considerable interest in applying sensor array signal processing techniques to a variety of applications in the fields of radar, sonar, communications, and remote sensing, amongst others. 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 outlines the requirements, design and development of an adaptive array processing toolset (AdAKT), 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 requirements for a graphical user interface to AdAPT.
