Synchronization Signal Interference Analysis for Tandem-L

Inhalt:
Tandem-L is a highly innovative mission concept with two radar satellites with reflector antennas to acquire data for Earth system science. The bi-static acquisitions require a synchronization of the satellites which will be ensured by exchanging radar pulses via synchronization antennas. The synchronization signal can additionally reach the SAR antenna. This paper analyzes the impact of the synchronization signal on the SAR antenna. Also, the SNR of the synchronization link is investigated to determine an acceptable trade between the synchronization SNR and low interference on the SAR antenna for different synchronization antenna orientations.
