Introduction

Passive Location Method Based on Phase Difference Measurement presents groundbreaking information for developing passive positioning technologies. The author has put forward a series of innovative solutions from the perspective of engineering application theory with the aim of giving a basic understanding of the application of unambiguous phase difference localization techniques for long-range passive detection.

On the basis of the existing linear solution of the double basis path difference positioning equation and the analysis of its intrinsic properties, this book starts from the study of the phase difference measurement method of the phase difference change rate, puts forward the concept of the differential function of the path difference per unit wavelength length and also discovers its jump law. It provides a possible way to solve the problem of unambiguous phase difference measurement. These results are of great significance to the development of passive localization techniques based on unambiguous phase difference measurement.

Key Features:
