Taschenbuch. Zustand: Neu. Neuware - In the outdoor measurement facility, a certain amount of real estate is owned by the organization, and therefore can be groomed to keep clutter contributions to a minimum. However, as the transmit signal travels further downrange, returns from long-range clutter sources are inevitable and can have signi cant impact on mea- surement accuracy. This research e ort investigates the e ectiveness of employing nonlinear suppression (NLS) to abate long-range ambiguous clutter in these facili- ties. In the simple two-pulse case, NLS requires a pulse repetition frequency which divides the radar's maximum range into two unambiguous ranges, and a transmit sig- nal comprised of alternating nearly orthogonal pulses.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Taschenbuch. Zustand: Neu. Neuware - Forward-Looking Airborne Radar (FLAR) Space-Time Adaptive Processing (STAP) has not achieved the same level of radar performance improvement as side- looking radar, because the ground clutter doppler-range dependence destroys the In- dependent and Identically Distributed (iid) assumption key to the STAP foundation. This thesis examines the Frequency Diverse Array (FDA), where each channel transmits and receives at a di erent frequency. The resulting range-dependent FDA antenna pattern is proposed to improve FLAR STAP performance. The planar FDA radar data model is derived and analytically veri ed to be equivalent to the constant frequency data model when each element frequency is set to the same value. The linear FDA at high platform altitude provides signi cant bene ts by reduc- ing the range ambiguous clutter contribution, improving target detection by 10 dB at the range ambiguous clutter notch.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Buch. Zustand: Neu. Neuware - The most complete compilation of millimeter-wave theory and data available, this book addresses those phenomenological characteristics of radar clutter and propagation in the millimeter-wave region that are of particular importance in the design, test and permutation of millimeter-wave sensors. The text provides in-depth information on both electromagnetic propagation and clutter backscatter effects in the millimeter-wave region. Nicholas C. Currie is also the editor of Radar Reflectivity Measurement: Techniques and Applications and Principles and Applications of Millimeter-Wave Radar.…

Buch. Zustand: Neu. Neuware - The material presented in this book is intended to provide the reader with a practical treatment of Weibull distribution as applied to radar systems. Topics include general derivation of Weibull distribution, measurements of Webull-distributed clutter, comparison of Webull distribution with various distributions including Rayleigh, gamma, log-normal and k- distributions, constant false alarm rate (CFAR) detectors for Weibull clutter, non-parametric CFAR detectors, and signal detection in the time and frequency domains. In particular, the Akaike Information Criterion (AIC), which is a rigorously mathematical fit of the hypothetical distribution to the data, is emphasised. This book is written primarily for radar engineers. It is hoped that it will also be of value to teachers and graduate students and of interest to all who are working with Weibull distribution in various fields.…
