This paper aims to find an appropriate approach to improve estimation accuracy of bearings-only tracking (BOT) and Doppler bearing tracking (DBT) by making use of the constraint on target speed. Targets usually travel within a valid speed zone so this contextual information (speed inequality constraint) should hypothetically help tracking algorithms (filters) achieve better accuracy. However the inequality...
The interacting multiple model for out-of-sequence measurements with acoustic and electro-optic (EO) fusion bearings-only tracker (IMMOOSM-AE-BOT) has been developed recently to track maneuvering targets from delayed acoustic sensor measurements and non-delayed EO sensor measurements on the same single platform. In this paper, we extend the IMMOOSM-AE-BOT to make use of frequency measurements from...
