2020 IEEE 40th International Conference on Electronics and Nanotechnology (ELNANO)

Abstract

One promising method for determining of an unknown radio source coordinates using wireless sensor networks is Angle of Arrival method based on MIMO technology. Using the mathematical apparatus of Kalman filtering, the algorithm is developed, which after forming initial conditions on the basis of determining of radio sources location from one pair of sensors, allows to recurrently determine its location in a rectangular coordinate system as data from other pairs of sensors are received. The efficiency analysis of the algorithm is performed using the statistical simulation. The application of the recurrent algorithm allows to reduce the RMS errors of radio source position estimation by 1.75-6 times.
