Multi-Information-Assisted Bistatic Active Sonar Target Tracking for Autonomous Underwater Vehicles in Shallow Water

Remote Sensing
Bistatic active sonar enables robust and precise target position and tracking, making it a key technology for autonomous underwater vehicles (AUVs) in underwater surveillance. This paper proposes a multi-information-assisted target tracking algorithm for

Active ABF for sonar [PDF]

Proceedings of 27th Asilomar Conference on Signals, Systems and Computers, 2002
An adaptive beamforming (ABF) algorithm tailored for active sonar is described. It is especially suited for processing FM waveform received by a fixed or moving sensor array. Adaptation is confined to small windows of time whose duration is closely related to the range resolution of the FM ping.

Research on high-resolution processing of frequency modulation combined signal for active sonar detection

Frontiers in Physics
The Frequency Modulation Combined (FMC) waveform has delay (range)-Doppler (velocity) coupling resolution, and the traditional nonlinear high-resolution algorithms represented by Point-wise Product (PP) and Point-wise Minimization (PM) have good anti ...
