A Registration Algorithm of Sensor System Errors Based on Innovation Correlation

Abstract:

In order to eliminate the influence of sensor system errors on detecting precision, the intersection of sensor locating globes is modeled with Earth-Center Earth-Fixed coordinates as transitional characters and to be eliminated, and a self-adaptive filter is presented to register sensor system errors for multi-platform, which identifies model characters and error characters on line by innovation correlation function sequence based on real-time mutual observation of platforms. Contrastive simulations against traditional registration algorithm show that the registration algorithm based on innovation correlation can converge quickly with high precision.
