Fast convergent robust range estimator for surface-to-air missiles

摘要

To cope with the intermittent unavailability of ground radar measurements due to jamming, a linear robust range estimation scheme utilising seeker measurements only is devised. Aside from the conventional approaches, it directly extracts range information from Doppler mismatch and line-of-sight rate measurements. The proposed filter shows good estimation performance and fast convergence with very small computational load.
