Handbook of Radar Scattering Statistics for Terrain by Fawwaz T. Ulaby – A Definitive Reference on Radar Scattering and

Introduction

The Handbook of Radar Scattering Statistics for Terrain by Fawwaz T. Ulaby is an authoritative reference work that has become indispensable for researchers, engineers, and students working in remote sensing, radar systems, and geoscience. Published by Artech House Publishers, this hardcover volume offers a comprehensive compilation of radar backscatter data and statistical models for various terrain types. For Indian students and professionals engaged in defence technology, agricultural monitoring, or environmental studies, this book provides the foundational knowledge required to interpret radar signals reflected from land surfaces. It bridges the gap between theoretical electromagnetics and practical terrain analysis, making it a vital resource for anyone involved in radar-based earth observation.

Book Overview

This handbook systematically presents measured radar scattering statistics for a wide range of natural and man-made terrain features. It covers important parameters such as backscattering coefficient, probability distributions, and correlation properties. The data is drawn from extensive experiments conducted over forests, agricultural fields, deserts, urban areas, and snow-covered regions. The book also includes models for surface roughness, soil moisture, and vegetation cover effects. Each chapter is structured to provide both raw data tables and analytical expressions, enabling readers to apply these statistics directly to their own radar system design or data interpretation tasks. The hardcover binding ensures durability for frequent use in labs and field stations.

Key Highlights

• Comprehensive Data Compilation: Over 200 tables of measured radar backscatter statistics for diverse terrain types, including Indian agricultural landscapes.
• Statistical Models: Detailed coverage of probability density functions, autocorrelation functions, and power spectral density models.
• Frequency and Polarization Dependence: Analysis of how radar response varies with frequency bands (L, S, C, X, Ku, Ka) and polarization (HH, VV, HV, VH).
• Terrain Classification: Systematic categorization of surfaces into bare soil, vegetation, snow, ice, urban, and water bodies.
• Experimental Methodology: Clear descriptions of measurement setups, calibration techniques, and error analysis used to gather the data.
• Practical Applications: Examples of how these statistics are used in synthetic aperture radar (SAR) image interpretation and target detection.

Inside the Book

The handbook is organized into ten major chapters. The opening chapter introduces fundamental concepts of radar scattering, including the radar equation and scattering mechanisms. Subsequent chapters delve into specific terrain categories: agricultural fields, forests, grasslands, arid regions, snow and ice, urban areas, and water surfaces. Each chapter presents statistical parameters such as mean backscatter, standard deviation, skewness, and kurtosis. The book also includes appendices with conversion factors, mathematical derivations, and a glossary of symbols. Numerous graphs and plots illustrate the variability of scattering across different incidence angles and environmental conditions. A special section on Indian monsoon-influenced terrain provides relevant data for regional studies.

Key Topics

• Backscattering Coefficient (Sigma Zero): Measurement techniques and typical values for different terrain types.
• Probability Distributions: Rayleigh, Weibull, log-normal, K-distribution, and gamma models for radar clutter.
• Surface Roughness Effects: Correlation between root mean square height, correlation length, and scattering behaviour.
• Dielectric Properties: Influence of soil moisture, salinity, and organic content on radar returns.
• Vegetation Canopy Modelling: Attenuation and volume scattering from crops, forests, and shrubs.
• Polarimetric Analysis: Decomposition techniques for identifying scattering mechanisms.
• Temporal Variations: Diurnal and seasonal changes in radar signatures due to weather and growth cycles.

Reader Benefits

• Accurate Data Reference: Eliminates the need to search scattered journals for reliable scattering coefficients.
• Improved System Design: Helps engineers optimize radar parameters like frequency, polarization, and incidence angle for specific Indian terrains.
• Enhanced Interpretation Skills: Enables better classification of land cover from SAR imagery used in Indian agricultural and forestry applications.
• Research Foundation: Provides a solid statistical base for developing new algorithms for target detection and terrain mapping.
• Time-Saving Resource: Consolidated tables and formulas reduce calculation time during project work or thesis research.

Learning Outcomes

By studying this handbook, readers will be able to: identify the dominant scattering mechanisms for different terrain types; select appropriate statistical distributions for radar clutter modelling; estimate backscatter values for given surface parameters; analyse the impact of frequency and polarization on radar returns; design experiments for collecting ground truth data; and apply the data to real-world problems such as flood mapping, crop monitoring, and urban planning. The book also equips readers to critically evaluate radar measurement errors and uncertainties, a crucial skill for Indian researchers working with indigenous radar systems like RISAT or NISAR.

Who Should Read

• Graduate Students: In electrical engineering, remote sensing, geography, and environmental science programmes at Indian universities.
• Radar Engineers: Involved in the design and testing of ground-based, airborne, or spaceborne radar systems.
