4. The reasons for the merger

There are two fundamental limits to the track fusion function: on the one hand, those linked to sensor physics, and on the other, those relating to operator capabilities.

4.1 Physical limitations of sensors

All sensors are limited in terms of the spectral range they cover and/or the angular sector they cover. For example, for a passive submarine sonar, it is physically difficult, if not impossible, to design a single antenna covering the 360° horizon from 10 Hz to 100 kHz: it is therefore necessary to equip the boat with several acoustic bases. Another case is when deployed sensors each have insufficient range to cover the entire area to be monitored without gaps. This situation is encountered in underwater detection (DSM), where a network of passive acoustic...
