Countless security and defense systems require an accurate Angle Of Arrival (AOA) detection for incoming signals. AOA estimation is basic procedure required by several monitoring and tracking systems for security applications and other defense purposes. In this paper, a combined OFDM system and band-pass sampling method using MUltiple SIgnal Classification (MUSIC) algorithm for automatic AOA tracking is discussed. And the authors propose a new method that adding Time Division Multiplexing (TDM) with band-pass sampling in the same time to avoid interference due to RF filter characteristics.
