Modern radar systems, especially those devoted to surveillance and defense mission, are able to accomplish different functions, change their operating modes and adapt the achievable performance according to the conditions and the peculiar environmental features (number and types of threats/tracks), in order to provide the optimal capabilities to cope/deal with. Those systems are, hence, demanded for high performance and high flexibility, allowing to save resources from not primary functions to be exploited to boost performances (resolution, search volume, detection range, renewal time, track refresh rates and initialization, etc.) of other proper functions according to the current needs of operation.
