Passive Location Method Based on Phase Difference Measurement presents groundbreaking information about passive location methods used for developing positioning technologies. The author has put forward a series of innovative solutions from the perspective of applied theory in distance finding with the aim of improving our understanding of systems designed to detect moving objects in small spaces.
The book starts with a theoretical study of the relationship between phase frequency functions on a two-dimensional plane. This is followed by explanations of detection methods using unambiguous phase parameters. The analysis demonstrates how difference change rates work with parameters for measuring phase difference and wavelength integers. In addition, there is a jump phenomenon between the difference term of phase difference and the difference value of the wavelength integer, that can be used to mathematically compute the distance between these parameters respectively.
The results in this work have interesting implications for location measurement with a lack of phase ambiguity. The methods show a framework for converting signal processing models for passive location detection systems for unambiguous phase difference calculations. It also provides an effective solution to the problem of how to eliminate the influence of the measurement error of the wavelength integer difference on the positioning accuracy.
