非相干散射信号处理新技术
Towards a new technique of incoherent scatter signal processing
摘要：
本文提出了一种新的非相干散射信号处理技术。该技术是基于实验观察到的梳状结构的光谱功率的单独实现。该技术意味着在单独的实现中确定峰值的位置和幅度，在它们的基础上形成不被平滑函数扭曲的单独实现的谱功率，以及随后对实现的这种谱进行求和。该技术已被测试使用的数据从伊尔库茨克非相干散射雷达，无论是从等离子体的热不规则性的非相干散射的情况下，从不稳定性的方面散射的情况下，延长与地磁场。
英文摘要：
This paper offers a new technique of incoherent scattering signal processing. The technique is based on the experimentally observed comb structure of the spectral power of separate realizations. The technique implies determining the positions and amplitudes of peaks in separate realizations, the formation - on their basis - of the spectral power of an individual realization not distorted by the smoothing function, and a subsequent summation of such spectra for the realizations. The technique has been tested using data from the Irkutsk incoherent scatter radar, both for the case of the incoherent scattering from thermal irregularities of plasma and for the case of the aspect scattering from instabilities elongated with the geomagnetic field.
