The big problem of MFAR functioning is energy and time budget distribution. Traditionally this problem solved at the system design time so the potential of MFAR could not be implemented. This paper provides approach to solve one part of this problem – evaluate surveillance function effectiveness online. Thus, this paper deals with single function efficiency in Multifunctional Array radar (MFAR). Novel approach of the surveillance function efficiency estimation is provided. It is based on critical range, and reaction time of radar. The search coverage and search volume are crucial radar parameters. Search period is the time period that is required for radar to search certain part of space. It reflects «information degradation» about targets’ positions in search volume in time. In MFAR with electronically steering beam where search function can be interrupted with other functions the «search period» definition lose its’ technical sense. Thus, information accuracy can be evaluate on-line according to the current search angle (beam number or beam angle), range (critical range) and «information degradation» factor.
