Abstract

In this paper, we assume that each range measurement has a bias error due to the clock offset or multipath propagation effect in a TOA (Time of Arrival) location system. We illustrate that we can estimate 3-dimensional target location and velocity only using Doppler measurements. We also illustrate that we can estimate target location, target velocity and range bias errors using range with bias error and Doppler measurements. We prove that there is not difference between both methods in terms of estimated location and velocity of the target. Here, we used Taylor series method.
