- The goal of this subject is to sum up and exploit our technique how to produce low phase noise wideband vcos , through investigating and studying the basic theory and recent research fruits , combining national condition , and produce our low phase noise wideband vcos . using high q components , such as : coaxial resonator , dielectric resonator , makes bandwidth of vco become narrower , so that recently common wideband vcos generally make inductor and capacitor ( lc ) as resonators , combining varactors with wide range tunable capacitance , and achieve the wideband
本课题旨在通过对低相噪宽带vco的基本原理、国内外在这方面的进展，结合国内的实际情况进行研究，总结和开发出自己的方法，形成自己的理论。并把它运用于实践，以制造出低相噪的宽带vco 。由于加入高q元件，如：同轴谐振器、介质谐振器等，会导致振荡器带宽比较窄，目前的宽带vco一般采用电感电容( lc )作为谐振元件，辅之以大变容范围的变容二极管，达到宽带的目的。 - Through the i 、 q component of ipix radar sea clutter data " s histogram analyses and by skewness and kurtosis computed , it is been shown that sea clutter amplitude is not rayleigh distribution ; through the comparison of amplitude histogram and distributed models with the same parameters , it is been shown that hh polarization clutter is lognormal distribution , whereas vv polarization is k - distribution ; at the same time the correlation function and power spectrum density are been analyzed , at last the correlation compound k - distribution stochastic sequences whose covariance matrix is been given are been generated through sirp algorithm
文中先介绍了海杂波幅度的有关模型,通过对ipix雷达海杂波数据的i 、 q分量的直方图以及倾斜度和峰度进行了分析和计算,证明了海杂波幅度不服从瑞利分布;使用幅度直方图和相同参数下的各种分布模型进行比较,得出hh极化符合对数正态分布,而vv极化服从k -分布的结论;同时对海杂波的相关函数和功率谱进行了分析,最后使用sirp算法产生了给定协方差矩阵的相关复合k -分布随机序列。
