A novel wireless positioning method employing an array of sensors which are capable of doing range estimates is proposed. Collectively, all the sensors in the sensor array can produce the direction of arrival (DoA) and the range information of mobile targets. To improve the positioning accuracy, it is proposed to introduce co-operations between the sensor arrays. Theoretical analysis and simulation results show that the use of the co-operation can increase the positioning accuracy significantly. Compared with other known methods, the proposed method does not require any phase measurement in the sensor arrays, so the system is relatively easy to operate and maintain. © 2012 IEEE.
