Abstract

In order to meet the goal of better tracking, selection of appropriate real time filter and modelling of, isturbances like process and measurement noise becomes a necessicity for a filter designer. In report, two filter schemes are evaluated to handle the polar .measurements using error' model (for bias ,correction and measurement noise covariance computation). It is assumed that a good reference source of target information is available. Particularly, Error model based Converted Measurement Kalman filter (ECMKF) and Error model based Modified13; Extended Kalman filter (EMEKF) algorithms are evaluated. Also some comparison with CMKF (de-biased) is given. The results are' presented for simulated data for target tracking. It is inferred that EMEKF gives better13; performance compared to other filters. Features of CMKF (de-biased), ECMKF, and EMEKF are brought out. Also the sensitivity study on the performance of EMEKF is done W.r.tto processing order of radar measurement channels
