Iterated Modified Gain Extended Kalman Filter with Applications to Bearings Only Tracking
نویسندگان
چکیده
A nonlinear filter called the iterated modified gain extended Kalman filter (IMGEKF) is presented in this paper. This filter uses bearings only measurements to estimate the target state in passive target tracking scenario. This work combines the MGEKF and the iteration method. The filter utilizes the updated state to re-linearize the measurement equation. Then the proposed work is tested in a two dimensional scenario. The simulation study compares the IMGEKF and some other filters to show the improvement.

متن کاملMathematical Modelling of Modified Gain Doppler Bearing Extended Kalman Filter for Underwater Tracking
The paper concerns the estimation of Target Motion Parameters (TMP) viz. Range, Bearing, Course and speed of a moving target, from noisy corrupted data. A sensor is used to obtain the Frequency and Bearing parameters of the target in this type of environment. The estimate of all TMPs is obtained by processing of these parameters data. Doppler Bearing passive target tracking is the determination...

متن کاملImproved Bearings-Only Multi-Target Tracking with GM-PHD Filtering
In this paper, an improved nonlinear Gaussian mixture probability hypothesis density (GM-PHD) filter is proposed to address bearings-only measurements in multi-target tracking. The proposed method, called the Gaussian mixture measurements-probability hypothesis density (GMM-PHD) filter, not only approximates the posterior intensity using a Gaussian mixture, but also models the likelihood functi...
