Localizing wild chimpanzees with passive acoustics
Ecology and Evolution, 2022 Abstract Localizing wildlife contributes in multiple ways to species conservation. Data on animal locations can reveal elements of social behavior, habitat use, population dynamics, and be useful in calculating population density. Acoustic localization systems (ALS) are a non‐invasive method widely used in the marine sciences but not well established

Passive Localization of Scanning Emitters
IEEE Transactions on Aerospace and Electronic Systems, 2010 The joint estimation problem of the scan rate and the position of a scanning emitter is investigated. The proposed approach takes advantage of the uniform rotating motion of the antenna main beam as it sweeps across a number of separate receivers. A joint estimator is developed based on a nonlinear least-squares (NLS) estimation.
