为了正确识别雷达欺骗干扰,针对基于数字射频存储器(DRFM)及直接数字频率合成器(DDS)产生距离-速度同步拖引干扰的现代欺骗干扰机,根据干扰机的工作机理,理论推导并对比了理想距离-速度同步拖引干扰信号及实际干扰信号的频谱特征。发现实际干扰信号的最大谱线相对理想干扰信号会产生微小频偏并在幅度上有一定衰减,这一频域细微特征可以为雷达识别该类干扰提供依据。仿真实验验证了理论分析的结果。

Hurst’s memory that roots in early work of the British hydrologist H.E. Hurst remains an open problem in stochastic hydrology. Today, the Hurst analysis is widely used for the hydrological studies for the memory and characteristics of time series and many methodologies have been developed for the analysis. So, there are many different techniques for the estimation of the Hurst exponent (H). However, the techniques can produce different characteristics for the persistence of a time series each other. This study uses several techniques such as adjusted range, rescaled range (RR) analysis, modified rescaled range (MRR) analysis, 1/f power spectral density analysis, Maximum Likelihood Estimation (MLE), detrended fluctuations analysis (DFA), and aggregated variance time (AVT) method for the Hurst exponent estimation. The generated time series from chaos and stochastic systems are analyzed for the comparative study of the techniques. Then, this study discusses the advantages and disadvantages of the techniques and also the limitations of them. We found that DFA is the most appropriate technique for the Hurst exponent estimation for both the short term memory and long term memory. We analyze the SOI (Southern Oscillations Index) and 6 tree-ring series for USA sites by means of DFA and the BDS statistic is used for nonlinearity test of the series. From the results, we found that SOI series is nonlinear time series which has a long term memory of H = 0.92. Contrary to earlier work, all the tree ring series are not random from our analysis. A certain tree ring series show a long term memory of H = 0.97 and nonlinear property. Therefore, we can say that the SOI series has the properties of long memory and nonlinearity and tree ring series could also show long memory and non-linearity.

针对雷达距离门内同时存在目标信号与DRFM距离欺骗干扰信号时的干扰检测问题,本文提出了基于信号检测理论与凸优化理论实现该情形下的欺骗干扰检测方法。首先,结合干扰机存在转发时延的实际,研究以干扰误差角为测度衡量距离门内有或无距离欺骗干扰两种情形下信号的相似程度。其次,理论推导了DRFM欺骗干扰存在时的透视检测器与GLRT检测器解析解。最后,通过仿真实验给出多种条件下的检测性能曲线。实验结果表明,得到的检测器能够对DRFM量化位数较低的距离欺骗干扰实现正确检测。

创新思维的物化过程是创新思维主体的一种存在方式。创新思维一旦产生就对实践具有指导作用,并能够通过创新实践活动改变客观对象,对客观对象进行有序的分解和组合,从而创造出体现创新目的的新对象。从观念的对象到实在的对象的转化过程就是创新思维的物化过程。这个过程体现了创新思维历史的必然性、发展的曲折性和客观的风险性。
