A Real-Time UWB Location and Tracking System Based on TWR-TDOA Estimation and a Simplified MPGA Layout Optimization

This article designs and implements a 3D moving target positioning tracking system by using ultrawideband (UWB) technology. The result of the two-way ranging time difference arrival (TWR-TDOA) algorithm is adopted to in new resolution that resolve hyperbolic equations. proposed applied outdoor indoor scenarios. To minimize effect sensor layout, this proposes simplified multi-population genetic (MPGA) obtain optimum distribution anchors, which can rapidly reduce number search iterations. low stability TDOA scenarios, Kalman filter utilized improve accuracy good simulation achieved. test results show system’s error far less than other methods. whole has feature high precision, stability, complexity, cost.
