39. CONCLUSION:
Military radars are one of the most important
requirements during the wartime, which can be
used for early detection of ballistic missile and
also for accurate target detection and firing.
Radar system discussed here has a built in threat
evaluation program which automatically puts
the target in a threat sequence, and advises the
weapon crew which target can be engaged first.
Military reliance on radar system is essential &
forever !
