This paper presents a technique for the estimation and removal of sensor biases and sensor frame misalignment errors for netted 3-D radar systems. One radar is assumed to have no bias in its measurements, and no tilt errors in its reference frame. The algorithm involves a two stage process. The first stage involves estimating the bias of each sensor and removing the effects of that bias with the estimate. The second stage uses the `bias-free' sensor measurements to estimate the sensor frame tilt errors. Simulation results are presented to demonstrate the performance of this approach.
