Application of Centralized BLUE Filter in Netted Radar
摘要
Abstract
To solve the nonlinear measurements problem of target tracking by netted radar , a centralized fusion filtering scheme based on boest linear unbiased estimation (BLUE) principle is proposed.Assuming the fusion center as coordinate origin, the measurement equation of target location by multiple radars is given , the BLUE filter models for target tracking by multiple radars with spherical and polar measurements are derived separately .Theoretic analysis shows centralized BLUE filter framework can esti-mate not only converted measurements'statistical characteristic of single radar , but also the statistical characteristic of converted measurements from multiple radars , so it outperforms distributed BLUE filter in both tracking precision and filter credibility .Com-putation complexity of centralized BLUE filter is relatively low as well .Simulations for different target profiles show that the pro-posed algorithm is superior to others in tracking scene with different state noise levels , which makes it a competitive filtering track-ing method.关键词
