結束了在奧地利卡普芬博格的集訓之後，德里奧?羅西介紹了目前球隊各方面工作的進展情況，並預測拉齊奧在明年的意甲中仍將位居前列。This paper in simple introduce on groundwork of kar raimund popper, from to karl raimund popper of core think - knowledge point going to generalize key for karl raimund popper of openness nature of the three world theoretical and bearing of down - to - earth world or subjunctive world going to analysis, karl raimund popper of theoretical content derive soundly ; from to again, the discuss to karl raimund popper world three the oretical in the information use with identity groundwork
摘要本文在簡單介紹卡爾?波普爾的基礎上，就其核心思想知識論進行了歸納；重點對波普爾的三個世界理論的開放性和現實界與虛擬界的關系進行了分析，充分揭示了他的理論內涵；以此為起點，論述了波普爾世界3理論在情報學的應用及本體基礎。Firstly, according to the characteristic that the doppler frequency shift signal can be approximated as a single sinusoid signal, the extended sinusoid signal retrieval ( pisarenko and esprit ) methods are presented and signal state and measurement formulations are developed, so the kalman filter recursive method is got. the brief introduction of low velocity moving target doppler frequency shift signal wigner - ville transformation and wavelet transformation expression are presented in this paper. secondly, because the clutter is gaussian distribution, cumement and high - order spectrum based methods are presented and the simulation results prove their good performance to suppress gaussian clutter in low velocity moving target doppler frequency shift signal processing
一個方面是根據低速目標的多普勒信號可簡化為單一正弦波形式這一特點，得到了擴展的高斯色噪聲背景下的諧波恢復演算法，即高斯色噪聲中的pisarenko諧波恢復法和旋轉因子不變法（ esprit ） ；並推導了信號的狀態方程和觀測方程，進而得到基於卡爾曼濾波的遞推演算法對信號進行提取；本文還簡單的介紹了低速運動目標的多普勒頻移信號的wigner - ville變換與小波變換；另一個方面是針對雜波服從高斯分佈這一特點，提出了對接收信號求累積量和高階譜來對高斯雜波進行抑制。
