Abstract :
A scanning null-line phased array system is introduced and comparisons of the detection sensitivity are made among scanning null-line phased array system, fixed null-line phased array system and single source system. The results show that the scanning null-line system has higher detecting sensitivity (signal-to-noise ratio) than fixed null-line phased array system or single source system
