Approximated Maximum Likelihood algorithm (Sciuridae)

Local Knowledge Graph (18 entities)

Knowledge graph centered on Approximated Maximum Likelihood algorithm (Sciuridae) with 18 nodes and 41 connections. Top connected: focal animal sampling (Sciuridae), antipredator behavior, space use, VoxNet: an interactive, rapidly-deployable acousti, alarm communication.

Description

Uses array of wireless acoustic sensors with correlation envelope sum (CES) method to precisely locate sources of marmot alarm calls in field settings. Employs cross-correlation analysis and multilateration algorithms to determine call positions with sub-meter accuracy.

Typical Equipment

• VoxNet wireless sensor nodes
• microphones
• multilateration algorithm
• CES processing software

Output Measurements

• call source coordinates
• acoustic localization precision
• call timing
