Function:

Originally developed for high-fidelity, physics-based simulation of towed array response in the ONR PLUSNet acoustic surveillance program. Uses a Finite Difference model of towed array, coupled to the towing platform dynamic model for tracking the dynamic changes in the sensor configuration. Supports flexible and fixed line arrays and arbitrary volumetric arrays. Continuously publishes all array element locations and poses, subsequently used by uSimPassiveSonar and uSimActiveSonar for proper extraction of relevant impulse responses from the embedded acoustic model.
