Precision Improvement of Ranging Data Using an Adjustment Algorithm with Doppler Measurements

This paper proposes a new approach for improving the ranging precision using adjustment algorithm with doppler measurements. As a data processing technique, the proposed approach requires no additional supports of specifically designed hardware or software, which mainly takes advantages of the accurate doppler measurements. Simulations have been conducted and convincible results have been obtained, which validates the effectiveness of the proposed approach. Results also show that weights for doppler measurements should be carefully treated in practice, which would significantly affect the precision and coherency.
