本文总结了有关无线电波在电离层湍流结构上散射的一些经典概念。比较了 Batchelor 和 Driscoll & Kennedy 的光谱表示，并阐明了各种潜在示踪剂梯度的作用。研究了这些示踪剂对散射强度的影响的系统相似性和差异。讨论了湍流和背景参数对于雷达体积反射率的重要性。这项研究强调了在解释湍流和大气背景参数的反向散射雷达信号强度时，尽可能完整、可靠地测量这些参数的重要性。
In this paper some classical concepts regarding scattering of radio waves on turbulent structures in the ionosphere are summarized. Spectral representations according to Batchelor and Driscoll & Kennedy are compared and the role of various potential tracer gradients is elucidated. Systematic similarities and differences in the representation of the impact of these tracers on scatter intensity are investigated. The importance of turbulence and background parameters for radar volume reflectivities is discussed. This study highlights the importance of measuring these parameters as completely and reliably as possible when interpreting the strength of backscattered radar signal in terms of turbulent and atmospheric background parameters.
