Sensitivity of range localization in a multipath environment

A study is made of the sensitivity of range localization to several features, focusing on features recovered by temporal processing, and a metric that plays the role of an ambiguity function, now generalized to the multipath environment, is developed. In contrast with the matched wave-field approaches, which treat the channel as a black box, the modeling strategy effectively provides a manageable tool for understanding the role that different features can play in localization. Contour plots illustrate the sensitivity of ranging to the features and metric adopted
