A Y-shaped-array for Direction of Arrival Estimation Via Space-time Processing
Zuo Ji-zhang · Modern Radar · 2007
A new DOA estimation method is proposed for Yshaped array.With the array geometry characteristics,and adopting space-time processing and sampled data normalizing and weighting,this method solves the fuzzy problem of backward and forward directions.The method has good stability and low estimation variance even if the signal-to-noise ratio is quite low.Simulation results show the effectiveness of the method.
