Measurement Bias Estimation in the Problem of Target Tracking

Abstract: In the problem of target tracking, different types of biases can enter into the measurement collected by sensors due to various reasons. In order to accurately track the target, it is essential to estimate and correct the measurement bias. Considering practical backgrounds, the bias is assumed to be locally stationary Gaussian distributed and an iterative estimation algorithm is proposed. Firstly, a mechanism is established to detect whether the bias switches between different Gaussian distributions. Secondly,… Show more

“…This would essentially make the Kalman Filter usel ess; however, it is used very successfully in tracking, forecasting, self-driving cars, groundwater, and others. This is because there are ways to either correct the measurements prio r to applying the Kalman Filter o r improve upon the Kalman Filter to estimate th e different random erro rs and biases [17,18]. Th e bias may be treated s eparately through a two -step Kalman Filter and can either be fed b ack into the model where it is used to update the bi ased state estimation, or it is not fed back into the model [19].…”
