Abstract

This paper describes experiences and results from developing a basic signal and data processing simulation for a pair of GEO IR sensors observing the boost phase of Theater Ballistic Missiles (TBM). The goal of such a system is the detection of launched TBM, also against a cloud background, and the tracking from cloud break ideally up to boost-end. Two GEO satellites are used for stereo view of one and the same non-global limited Field-of-Regard (FOR). They are positioned in such a way that both cover the FOR and provide a sufficient triangulation baseline. Signal Processing is applied for each of both passive IR sensors in order to detect and track the TBM on the focal plane. The applied approach can be summarized under the term 'velocity filtering'. Data Processing operates on the 2-D signal processing input from both IR sensors, i.e. azimuth and elevation line-of-sight (LOS) angles as well as their rates. The goal is to provide 3-D tracks of the targets, which can be used to cue early warning or fire control radars. The underlying simulation model constitutes a prototype and vehicle for further research. Nevertheless, even in its current stage it provides a first tool for the analysis and evaluation of corresponding sensor design concepts.
