An on-orbit reconfiguration method for spaceborne SAR active components

Spaceborne SAR is increasingly using active phased array system, and the core of active phased array antenna is T/R component, the performance of T/R component directly affects the performance of spaceborne SAR.As the working life cycle progresses, the performance parameters of T/R components decay, In this paper, based on the collection of T/R component power supply state information, a reconfiguration method of spaceborne SAR active components in orbit is designed to achieve the maximum performance during the lifetime of spaceborne SAR.
