Artech House Publishers Practical Geolocation for Electronic Warfare
Book SynopsisThis text explores the practical realities that arise from the employment of geolocation for electronic warfare in real-world systems, including position of the target, errors in sensor position, orientation, or velocity, and the impact of repeated measurements over time. The problems solved in the book have direct relevance to accurately locating and tracking UAVs, planes, and ships. As a companion volume to the author’s previous book Emitter Detection and Geolocation for Electronic Warfare (Artech House, 2019), this book goes in depth on real-world complications that include: working within and converting between different coordinate systems, incorporation of prior information about targets, sensor uncertainties, the use of multiple snapshots over time, and estimating the current position and velocity of moving targets. The e-book version described here includes several links to software and videos that can be downloaded from the publicly available Git repository. The book also includes all MATLAB code necessary to develop novel algorithms that allow comparisons to classical techniques and enable you to account for errors in timing, position, velocity, or orientation of the sensors. With its unique and updated coverage of detailed geolocation techniques and data, and easy linkable access to additional software and videos, this is a must-have book for engineers and electronic warfare practitioners who need the best information available on the development or employment of geolocation algorithms. It is also a useful teaching resource for faculty and students in engineering departments covering RF signal processing topics, as well as anyone interested in novel applications of SDR’s and UAVs.Table of ContentsChapter 1 Introduction 1 1.1 Receiver Processing 1 1.2 Geolocation 2 1.2.1 Practical Considerations of Geolocation 3 1.3 Associated Software 9 1.3.1 MATLAB 9 1.3.2 Textbook Software 10 1.3.3 Python Software 10 Chapter 2 Review of Emitter Geolocation 13 2.1 Geolocation Measurements and Their Likelihood Functions 13 2.1.1 Likelihood Function for AoA Measurements 14 2.1.2 Likelihood Function for TDOA Measurements 16 2.1.3 Likelihood Function for FDOA Measurements 17 2.1.4 Likelihood Function for Hybrid Measurements 19 2.1.5 Generating Measurements and Likelihood Functions 20 2.2 Estimators 25 2.2.1 Maximum Likelihood Estimation 25 2.2.2 Maximum a Posterior Optimization 26 2.2.3 Convex Optimization 26 2.2.4 Least Square Estimators 27 2.2.5 Using Estimators for Geolocation 28 2.3 Other Geolocation Algorithms 31 2.4 Performance Measures 31 2.4.1 Root Mean Squared Error (RMSE) 31 2.4.2 Error Ellipse 32 2.4.3 Circular Error Probable (CEP) 32 2.4.4 Statistical Bounds 33 2.4.5 Statistical Bounds for Common Geolocation Data 36 2.4.6 Calculating CRLB for Geolocation Measurements 38 2.5 Discussion 39 2.6 Problem Set 41 Chapter 3 Sensor Selection 45 3.1 Measurement Sets 47 3.1.1 Full Measurement Set 47 3.1.2 Non-Redundant Set 48 3.2 Measurement Statistics of Sensor Pairs 49 3.2.1 Sensor Pair Cross-Covariance 50 3.2.2 Usage 51 3.2.3 Generating Measurements 54 3.2.4 Jacobian Matrix of Arbitrary Sensor Pairs 56 3.3 Performance Analysis 57 3.4 Problem Set 66 Chapter 4 Coordinate Systems 69 4.1 Local Coordinate Systems 69 4.1.1 Cartesian Coordinates 69 4.1.2 Spherical Coordinates 71 4.2 Global Coordinate Systems 73 4.2.1 Models of the Earth 73 4.2.2 Latitude and Longitude 77 4.2.3 Earth-Centered-Earth-Fixed (ECEF) 78 4.2.4 Earth-Centered Inertial (ECI) 78 4.3 Usage 79 4.3.1 Conversion between ECEF and LLA 80 4.3.2 Conversion between ENU and ECEF 81 4.3.3 ENU Adapted for Spherical Earth 83 4.3.4 Examples 84 4.4 Problem Set 89 Chapter 5 Geolocation with Target Constraints 93 5.1 Geolocation with Known Target Altitude 94 5.1.1 Optimization Problem Formulation 94 5.1.2 Solvers 96 5.1.3 Performance Analysis 105 5.2 Geolocation with Known Altitude Bounds 111 5.2.1 Optimization Problem Formulation 111 5.2.2 Solvers 112 5.2.3 Performance Analysis 117 Contents ix 5.3 Geolocation with Statistical Priors 117 5.3.1 Example Priors 119 5.3.2 Solving Geolocation with Priors 119 5.3.3 Performance Analysis 122 5.4 Problem Set 124 Chapter 6 Geolocation with Sensor Uncertainties 127 6.1 Formulation 127 6.1.1 Gradient of the Measurement Function with Sensor Uncertainties 132 6.1.2 Sensor Position Covariance 138 6.2 Approach 143 6.2.1 Required Observations 144 6.2.2 Maximum Likelihood 146 6.2.3 Iterative Solvers 151 6.3 Calibration Emitters 154 6.3.1 Measurement Bias Estimation 155 6.3.2 Sensor Position Error Estimation 157 6.3.3 Estimating Target Position 157 6.4 Other Solution Approaches 160 6.5 Performance Analysis 161 6.6 Problem Set 163 Chapter 7 Geolocation with Multiple Snapshots 167 7.1 Introduction 167 7.2 Convergence of Multiple Measurements 168 7.2.1 Measurement Space Solutions 172 7.2.2 State Space Solutions 176 7.3 Geolocation of a Stationary Target from Moving Sensors 182 7.3.1 Measurement Space Solutions 183 7.3.2 State Space Solutions 183 7.3.3 Complex Scenarios 186 7.3.4 Degenerate Geometries 188 7.4 Conclusion 190 7.5 Problem Set 190 Chapter 8 Geolocation of Moving Targets 193 8.1 Introduction 193 8.2 An Introduction to Tracking 193 8.2.1 Update Stage 194 8.2.2 Prediction Stage 196 8.2.3 Limitations 197 8.2.4 Coordinate Selection 197 x Contents 8.3 State Space Models 198 8.3.1 State Space Representation of Targets 198 8.3.2 Kinematic Models 198 8.3.3 Process Noise 201 8.3.4 Measurement Models 202 8.4 Advanced Tracking Concepts 212 8.5 Problem Set 216 Appendix A Derivation of the Fisher Information Matrix for Phase, Delay, and Doppler Estimation 221

Special Interest Model Books Scanners 7: Tuning Into Digital & Analogue Communication
The 'Scanners' series of books have been consistent bestsellers, being the UK's leading guides to receiving equipment employed by enthusiasts to monitor the short wave and VHF/UHF wavebands used by airfields, maritime and rescue services, and analogue and digital two-way private mobile radio systems. This new (seventh) edition covers the rapidly increasing trend towards digital two-way radio communications and the latest handheld and mobile/base scanners with some digital modes fitted. It has been fully re-written and updated to include the latest UK radio frequency listings and call signs for airports, maritime and emergency services and other professional organisations. The book covers the latest shifts in the hobby towards digital and PC- and tablet-controlled radio technology and illustrates the very latest commercial radio scanning equipment and accessories. Included are details of an increasing number of 'apps' for smartphones specifically for radio data decoding, including programs for digital scanner communications decoding for which a smartphone can be linked to an existing scanner radio to decode. Other innovations include TETRA as used by police, ambulance, fire and rescue services, and DMR modes such as Mototrbo. It is predicted that by 2016, fifty per cent of two-way radio communication in the UK will use digital modes.

Monsoon Books Snow over Surabaya
Book SynopsisNot many British schoolgirls have grown up to become revolutionary heroes of distant, eastern nations but Muriel Stewart Walker did just that. Under a multitude of different names - 'K'tut Tantri' and 'Surabaya Sue' being the best know - she joined in the struggle for Indonesian independence after the Second World War and broadcast its revolutionary message to the world on Rebel Radio. But she did more and smuggled arms, and probably drugs, to help finance the new Republic and experienced bloody battle in the British attack on Surabaya that some have seen as a war crime. She went on to become an intimate of the revolutionary leaders and finally lived to see Indonesia take its place amongst the free nations of the world. Glaswegian 'Surabaya Sue' is virtually unknown in the West and, even in Indonesia, there have always been doubts about her version of events that many have dismissed outright as a blatant mixture of outrageous fantasy and dishonest omissions. Snow over Surabaya happily embraces those doubts and brings a new, spirited account of her adventures in that tempestuous world.
