Abstract :
We formulate the sensor alignment problem for multisensor data fusion in the ECEF coordinate system. Sensor measurements are mapped to the ECEF coordinate system using geodetic transformation and sensor registration errors are estimated using the least squares (LS) technique. Real life-radar data are used to evaluate the performance of the proposed technique.
