Sensor registration technique for passive location system

A general least-squares (GLS) passive sensor registration algorithm is studied for passive location system. At first, the position error model of passive location system is proposed; then, based on the error model, a linear measure model is constructed for the angle system error of passive sensor, and the GLS is utilized for estimating the biases. Simulation results show that the method can effectively estimate the angle biases for passive location system. (4 pages)
