This paper describes the study of bat echolocation signals using high resolution spectral analysis methods such as minimum variance estimator (MVE) and instantaneous frequency IF based analysis. The techniques reported in this paper is demonstrated to be capable of showing previously unseen features in the call structure of bat echolocation. It should be emphasised that although the study is focused on bat echolocation signals, the results are more generally applicable.
