About this book

This book highlights new methods and parametric algorithms for the digital coherent processing of signals in airborne radar systems located on air vehicles. Using the autoregressive (AR) model, it delivers more accurate danger assessments for flight in wind shear and atmospheric turbulence, while also suggesting how they could be implemented. Given its scope, the book is intended for technical experts whose work involves the development, production and operation of airborne radio-electronic systems.

Chapter 1. The Detection and Assessment of Meteorological Object Parameters by Airborne RS

Abstract
One of the most commonly occurring adverse environmental conditions in the practice of AV flights leading to consequences, dangerous on the influences on AV are various perturbations of the atmosphere (Table 1.1) [15].

Chapter 3. The Methods and Algorithms of Processing of Signals Improving Observability and Accuracy of the Assessment of Parameters of Meteorological Objects of Airborne Radar Stations

Abstract
A big variety of conditions of formation of the signals reflected by MO causes essential aprioristic uncertainty of their parameters that does not give the opportunity of use of any known in advance characteristics for the organization of optimum processing of these signals, for example, by Bayesian methods or by the methods of maximum of posteriori density of probability.

Chapter 4. Conclusion

Abstract
The monograph is devoted to improvement of methods and algorithms of processing of signals in airborne aviation radar systems (RS) for increase in the flight operation safety (FOS) in difficult meteoconditions.
