Radar Design Principles: Signal Processing and the Environment

Front Cover
Provides a broad look at modern theory as well as a review of all the developments in practical equipment design and construction in recent years. This resource includes four chapters on detection theory, plus seven on waveforms and signal processing. Other chapters include essential data on radar targets, background, and propagation. Throughout, the emphasis is on radar design to cope with the 'total environment', including unwanted reflections from sea, land, precipitation, chaff, thermal noise, and jamming, rather than using simplified or fragmented design discussions as found in most other text of this type. The author also recognizes that mapping, weather-sensing, terrain avoidance, altimetry, etc. may be designed for single-function radar or as modes of a multifunction radar. The last chapter in the book identifies newer, more specialized radar techniques, such as space-based radar, and describes how to analyze or simulate coherent radars including the limitations and related loss terms.Key features include: Radar targets: detailed treatment of scattering from simple and complex shapes, polarization properties, radar cross-section distributions, and frequency agility effects. Propagation, atmospheric effects, weather and chaff: includes coverage of signal attenuation and scattering in the atmosphere, in precipitation, and in foliage, Backscatter coefficients, uniformity, and spectrum, refraction, and properties of chaff. Sea and land scattering: greatly expanded treatment of backscattering from the sea and land as a function of angle, frequency, polarization, and pulse width, including the properties of sea 'spikes', the effects of ducting conditions on both sea and land reflectivity.
