Editorial: Multi-sensor signal processing for defence: Detection, localisation & classification

Multi-sensor signal processing is fundamental not only to civilian applications but also to the capability of many defence systems. This special issue presents a collection of research papers that address a number of "hot topics" broadly concerned with the development of new multisensor signal processing algorithms. These algorithms aim to exploit the benefits offered by multi-sensor systems, while addressing the issues resulting from military sensor signals which provide both excellent opportunities and significant research challenges.
