Acoustic propagation delay has not been investigated for a continuous wave multistatic sonar tracking system except for the recent study conducted by Jauffret et al. [4], which estimates the trajectory of a constant velocity target. The results showed that the estimate bias caused by the propagation delay is not negligible, especially for a bistatic system. This paper develops an interacting multiple...
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...
The performance of the conventional bearings-only tracking (BOT) from a single passive sensor largely depends on the sensor platform maneuvers. This paper presents a new BOT approach based on fusion from two heterogenous bearings-only sensors residing on the same moving or stationary platform. The two sensors are an ESM/EO with negligible propagation delay and an acoustic sensor with significant propagation...
Acoustic tracking with propagation delay is a challenging problem due to the following reasons: 1) It is difficult to perform an accurate state prediction, as the time interval between the current state and the previous state is varying and unknown due to the propagation delay; 2) The target time (signal emission time) needs to be estimated in addition to the target position and velocity. With the...
