Abstract(in English) | Statistical analysis techniques for estimation of three dimensional (range, elevation and azimuth) radar biases, using a six-order Kalman filter, are presented in a two-radar system. It becomes clear that the radar biases can be uniquely determined provided that observation matrix has full column rank, even though observation matrix is a nonlinear function of position measurement vector and a priori estimates of radar biases. But our computer simulation results show that there is a case where the radar bias estimation errors are unbounded. Even in the divergence case, observation matrix has full column rank. Therefore, we present new condition of accurate radar bias estimation. This condition is that the minimum eigenvalue of a matrix H^TH is sufficiently larger than zero, where H is the observation matrix and H^T indicates transpose of matrix H. |
