Paper Abstract

The use of IR search and track (IRST) sensor is now generally accepted as essential on board ships but their angular 2D target reports are sometimes insufficient when electromagnetic control plans are in use in naval operations. The principle of an on-board 'Quite Silent Search Function' (QSSF) consists in fusing reports from an IRST sensor and a MultiFunction Radar (MFR) with controlled emission to obtain an acceptable covertness level, while having very accurate 3D target indication to the combat system. The main idea pushed ahead consists in tolerating a reduced level of radar emission in order to counteract the ARm tracking capability and to reduce adverse ESM detection. The paper addresses this situation and shows the main contribution of a QSSF compared to standard Search Function using an IRST placed in no false alarm conditions and then in severe false alarms conditions. Statistic performances of the QSSF are provided; they have been obtained through Monte-Carlo analysis using a hybrid simulator. Thus, the IR clutter is compared of true IRST signal recordings while radar clutter and target contact reports are synthetic.
