A Registration Algorithm of Sensor System Errors Based on Innovation Correlation

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.
