IET Radar, Sonar & Navigation, 2021 Among so‐called active sensors that use self‐generated signals, sonar sensors are more challenging to implement than lidar and radar due in part to their limited angular field of sensing. A common solution to this challenge is scanning sensors that sweep

Deep‐learning‐based line enhancer for passive sonar systems
IET Radar, Sonar & Navigation, 2022 Detection of acoustic tonals from surfaces and underwater vehicles is important for passive sonar systems. Enhancements of the tonals are usually necessary in passive sonar prior to detections.

Passive Sonar Target Tracking Based on Deep Learning
Journal of Marine Science and Engineering, 2022 At present, the tracking accuracy of underwater passive target tracking is often limited due to models that are overly simple, with low complexity, poor universality, and an inability to learn.

Tracking the Tracker from its Passive Sonar ML-PDA Estimates [PDF]
, 2013 Target motion analysis with wideband passive sonar has received much attention. Maximum likelihood probabilistic data-association (ML-PDA) represents an asymptotically efficient estimator for deterministic target motion, and is especially well-suited for

Simulated Research on Passive Sonar Range Using Different Hydrographic Conditions
MATEC Web of Conferences, 2015 As an example using the passive sonar, it calculated the quality factor of passive sonar using the sonar equation. The sound field was calculated under different depth and range using multiform hydrographic conditions.

A risk function for behavioral disruption of Blainville's beaked whales (Mesoplodon densirostris) from mid-frequency active sonar. [PDF]
PLoS ONE, 2014 There is increasing concern about the potential effects of noise pollution on marine life in the world's oceans. For marine mammals, anthropogenic sounds may cause behavioral disruption, and this can be quantified using a risk function that relates sound

IEEE Access, 2023 For decades, the soft-kill strategy which detects high-speed underwater targets with passive sonar and attract the targets using decoys has been used. However, recently, the paradigm to respond to the high-speed underwater targets is shifting to a hard ...
