Military radar
It is a military electric device utilizing electromagnetic wave for exploration. The electromagnetic wave launched by radar irradiates the target and receives the echo. By this way can it discover the target and search the location, motor direction, running speed and other features. Given that it needs to meet the special requirements on military, it is necessary for the backup battery to provide constant power at -40℃ and satisfy the examination standard of combating and shooting.
