  • 起始頻率

Examples

  • In addition , based on fft and remainder algorithm , the modulation rate and initial frequency of sub - sampling uwb lfm signal are estimated unambiguously in negative snr
    該方法通過fft和余數(shù)定理解頻率模糊,解決了負(fù)信噪比條件下超寬帶線性調(diào)頻信號調(diào)制斜率和初始頻率的估計(jì)問題。
  • Simulations with respect to two models , prove that the method can track the frequency accurately and instantly , and have the preferable effectiveness on the abruptly fluctuating - frequency power signals , at the same time , this method overcomes the constraint of synchronous sampling and has the better astringency with different initial frequency
    針對兩種模型進(jìn)行仿真，表明該方法能夠較為精確與快速地跟蹤電網(wǎng)頻率，尤其針對突變頻率的信號，具有較好的跟蹤效果；同時算法克服了同步采樣條件的限制，通過迭代，在不同初始頻率下均具有較好的收斂性。
  • One new method that the uwb signal can be received ambiguously has been presented in this dissertation . furthermore , the sampling lfm signal becomes two sine signals with different frequencies based on two different delay processes . based on fft and remainder algorithm , the modulation rate and initial frequency of sub - sampling lfm signal are estimated precisely and unambiguously in negative snr
    該方法通過在數(shù)字域?qū)π盘栠M(jìn)行兩路不同的延時和余數(shù)定理實(shí)現(xiàn)欠采樣條件下超寬帶線性調(diào)頻信號的調(diào)制斜率和初始頻率的無模糊估計(jì),在不降低參數(shù)估計(jì)精度的前提下,解決了欠采樣方法引起硬件復(fù)雜度增加的問題。
  • Without deteriorating accuracy of estimated parameters , this method needs less hardware . 4 . based on esprit algorithm and remainder algorithm , the modulation rate and initial frequency of sub - sampling uwb lfm signal can be estimated unambiguously and precisely in a low snr background
    4 、研究了一種基于欠采樣和esprit算法的超寬帶線性調(diào)頻信號的調(diào)制斜率和初始頻率的參數(shù)估計(jì)方法,把具有優(yōu)越性能的esprit方法運(yùn)用于欠采樣條件下的超寬帶線性調(diào)頻信號的參數(shù)估計(jì)中。
  • After the compensation based on the rule of the minimum entropy , the resolution of the cross - range image is lower as the large size and non - uniform rotation , which cause the image to be not right at all sometimes . in order to eliminate effect of the non - stationary rotation , the first order approximation and relax algorithm are adopted to search the initial frequency , amplitude , frequency modulation rate and obtain the dynamic image of the target at any time
    分析了低分辯雷達(dá)的成像算法，建立在最小熵補(bǔ)償基礎(chǔ)上的算法得到的橫向像的分辨率仍然比較低，尤其對大的目標(biāo)和機(jī)動目標(biāo)，為此我們采取了一階近似的relax算法搜索目標(biāo)的初始頻率、幅度、解調(diào)率從而獲得目標(biāo)的動態(tài)一維像，仿真數(shù)據(jù)和試驗(yàn)結(jié)果證明該方法是有效的。
