Method for received signal strength-based direction-of-arrival location estimation for wireless target in an indoor environment is disclosed. The method can use just one DOA sensor node with three antennas, configured substantially in the center of a predetermined confined indoor space. Packet signals can be transmitted by DOA sensor node to the wireless target, and vice versa, where each packet comprising of a fixed sensor node cover range. RSSI values are obtained for the respective RSSI states received from the wireless target at incident angles phi using the triangular antenna array, a 1P2T switch, and a vector signal deconstructor (VSD). A location (theta, phi) of the localized object is calculated using a RSS-based DOA algorithm. A RSS to DOA localization system using the above method is also disclosed.
