We consider the model of a mixture of probability distributions for background and target samples in the problem of extracting a signal from radiophysical sounding under conditions of a priori nonparametric uncertainty. Based on the study of this model, approaches relying on the risk function and selection of anomalous readouts in the sample are proposed for detection and extraction of a continuous ionosonde signal. Semi-empirical modeling and testing by experimental data are performed.

在先验非参数不确定性条件下检测啁啾离子探空仪信号

在先验非参数不确定性条件下从无线电物理探测中提取信号的问题中，我们考虑了背景和目标样本的混合概率分布模型。基于对该模型的研究，提出了依赖于风险函数和样本中异常读数选择的方法来检测和提取连续的离子探空仪信号。通过实验数据进行半经验建模和测试。
