导出了雷达接收信号统计量与散射介质密度起伏统计量之间的一些基本函数关系。它们的普遍性程度各不相同，但它们的范围都很普遍。它们包括从大气、电离层或气象介质散射的单基地和双基地雷达。它们适用于折射和微色散介质，因此也可用于高频电离层雷达。它们包括滤波的影响，包括接收器滤波、脉冲压缩编码和解码方案、相干积分或任何替代的线性数字滤波方案。函数关系，包括互相关计划，如法拉第旋转实验和干涉仪，包括在内。一些简化的表达式推导出经常遇到的情况下，可以作出不同的近似。这些简化的表述涵盖了目前用于大气层和电离层应用的大量雷达技术。
Some basic functional relationships between the statistics of the signals received in a radar and the statistics of the density fluctuations of a scattering medium are derived. They vary in their degree of generality, but they are all very general in scope. They include monostatic and bistatic radars scattering from either atmospheric, ionospheric, or meteorological media. They are valid for refractive and slightly dispersive media, so they can also be used for HF ionospheric radars. They include the effects of filtering, including receiver filtering, pulse compression coding and decoding schemes, and coherent integration, or any alternative linear digital filtering scheme. Functional relationships to include cross-correlation schemes, such as Faraday rotation experiments and interferometers, are included. Some simplified expressions are derived for frequently encountered situations, where different approximations can be made. These simplified expressions cover a large number of radar techniques currently in use for atmospheric and ionospheric applications.
