New registration algorithm of sensor in ECEF coordinate system

An algorithm is presented to absolutely registration two 3-D sensors using targets that are tracked by both sensors. The algorithm estimates and removes sensor biases and sensor frame orientation errors, For illustrative purposes, the algorithm uses the difference in the position of a target, as reported by the two sensors, to compute a set of bias parameters. These bias parameters are then applied to align both sensorpsilas track positional data. The registration algorithm is applicable to those situations where there are no sensor location errors, the magnitude of the bias errors is small, and these errors do not change with time or very slowly with time.
