  • Patent number: 4123757
    Abstract: The present invention relates to a radar sector scan apparatus which reves its direction of scan without causing large current spikes in the scan-producing motor. This result is achieved by switching off the motor before the instant at which the scan direction is reversed and letting the momentum of the antenna (attached to the motor shaft) continue the scan. Spring and bumper means are provided for slowing, stopping, and then reversing the scan while the motor is off. A switching arrangement is provided which switches off and switches on the motor at the appropriate times to effect smooth scanning and scan reversal. The invention also includes automatic start up logic.
