Abstract :
The switch antenna array (SAA) is a promising substitute for multi-channel antenna array (MAA) due to its low cost, small volume and high resolution. The current signal processing method is efficient only in the low velocity and low frequency case. A new 2-dimension method is proposed, which is suitable to bearing estimation of moving objects without any restriction on their velocity. This method also enhances the resolution capacity of SAA
