Abstract Monitoring the weak ocean surface current is one of the most important applications for microwave remote sensing. It is significant for both civil and martial maritime activities. Signal Clutter Ratio (SCR) between ocean surface weak current and wind-generated waves is defined, in the frame of which the optimal configurations of RAR/SAR/biSAR with parallel flight squint mode are studied, under wind speed statistical distributions in South China Sea. The comparision results among the SCRs of the three sensor systems show that RAR, with the highest SCR, is the best system for weak ocean surface current observation.
