Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a system for multi-channel synchronization control.
Background
The traditional solid-state phased array antenna is an antenna of a transceiving time division system, the width of transmitting pulse is wide and is at least microsecond, the transmitting synchronization of transceiving components of a full array surface of the solid-state phased array antenna is realized by a microwave feed network, namely, a single path of microwave excitation signal which is input to the solid-state phased array antenna in a frequency synthesis mode is amplified on the array surface of the solid-state phased array antenna in a multi-stage mode and is finally input to the front end of the transceiving components of the full array surface in equal length paths.
The transmitting pulse sent by the beam control device to the receiving and transmitting components with a plurality of full array surfaces does not reach a strict synchronization relation with the radio frequency excitation of the frequency synthesis to the solid-state phased array antenna in the time domain, and the transmitting pulse sent by the beam control device in a control circuit is advanced for a plurality of microseconds than the excitation pulse signal output by the frequency synthesis, and the rear edge lags behind for a plurality of microseconds. The design ensures that the power of the transmitting power amplifier in the transceiving component is powered up and completed before the microwave excitation signal arrives, and ensures that the power amplifier in the transceiving component is not in a receiving state during the trailing period.
Although the transmission requirements of most phased array antennas can be met by using the form, when the power consumption of the transceiving component is large and the transmission pulse is widened during transmission, the fact that power is required to be applied in advance means that the working efficiency of the transceiving component is seriously influenced if the power application time is too much, and the traditional wave beam control device is not suitable for the requirement of extremely narrow transmission pulse because the control magnitude of the width of the transmission pulse is more than one hundred nanoseconds.
