Narrowband Passive Sonar Tracking
Passive sonar sensors are the main source of information for a submerged submarine. Modern sonar systems like ISUS 90 offer a number of acoustic antennas and combined signal processing for broadband and narrowband detection and analysis of target noise. While broadband detection is often used to obtain an overview of the targets surrounding the own ship, narrowband processing enables the detect...
متن کاملML-PDA and ML-PMHT: Comparing Multistatic Sonar Trackers for VLO Targets Using a New Multitarget Implementation
The Maximum Likelihood Probabilistic Data Association (ML-PDA) tracker and the Maximum Likelihood Probabilistic Multi-Hypothesis (ML-PMHT) tracker are applied to five synthetic benchmark multistatic active sonar scenarios featuring multiple targets, multiple sources and multiple receivers. For each of the scenarios, Monte Carlo testing is performed to quantify the performance differences betwee...
متن کاملPassive Sonar Tracking Using Received Signal Amplitude Fluctuations
We present a passive sonar tracking algorithm that utilizes variations in the amplitude of the signal received from a source in motion. The approach is model-based in that it employs an acoustic propagation computer program, and Bayesian in that prior knowledge is used to compute a posterior probability distribution function from which the target location is estimated. The algorithm is designed...
متن کاملPassive Sonar Performance Modeling
Accurate passive acoustic (ASW) performance modeling requires high-fidelity environmental inputs, accurate acoustic propagation and noise modeling as well as the integration of the statistics of the detection of quiet signals in a dynamic environment. In this paper we present the combination of Parabolic Equation modeling with state of the art statistical signal processing to be able to incorpo...
متن کاملPassive SONAR Equation Intro
For the rest of the semester, we will take a closer look at each of the components of the passive SONAR equation. The goal is for each of you to enhance your understanding about each of the components and understand what actions can minimize or maximize the factors as appropriate to your tactical undersea warfare situation. Undersea warfare is a complex process where those with the best underst...
