• Combined with electromagnetic and heat transfer , fem ( finite element method ) are used to analysis the temperature distribution in the output window result from pulse microwave and consecutive microwave of high power
  用有限差分法对回旋管输出窗在连续波功率、脉冲功率条件下的温度分布进行了计算和分析。四
• In the spread spectrum communication , the continuous - waves signal is transmitted . this kind of random time - variety may cause the varieties of the amplitude , doppler frequency and the phase of the received signal
  在扩频通信中,传送的是连续波信号,这种随机时变性会使接收信号的幅值、频率和相位都发生变化。
• To the principle of single - station high - frequency ground wave detection radar , simple pulse wave was chosen , but this wave has many limitations , so continuous signal wave was preferred
  从雷达信号波形选择来看,对于单站高频地波超视距雷达体制,最初采用简单脉冲波形。但这种波形存在着许多缺点,最终采用连续波信号体制。
• By comparing to that of bbo , we can see that the threshold of clbo is lower than that of bbo . thus clbo provided another excellent crystal in dro if the pump power is low
  从结果可以看出，在平面波双谐振下， clbo晶体的振荡阈值低于同等条件下的bbo晶体，从而为连续波、长脉冲等能量较小的泵浦源提供了更加优良的可选晶体。
• Lfmcw echo is modulated by doppler frequency . according to the characteristic , moving targets with different ambiguous velocities could be classified via mtd , but the range - velocity coupling problem still exists
  线性调频连续波雷达回波同脉冲雷达一样受到了多普勒频率的调制，通过动目标检测( mtd )可抑制杂波，检测运动目标。
• In this thesis , aimed at the above - mentioned two - side problems , based on analyzing the theory of lfmcw radar ranging deeply , we implement the work of intermediate frequency signal processing
  本论文针对上述两方面的问题,在深入分析lfmcw雷达测距理论基础上,在工程上完成了一部8mm毫米波线性调频连续波测距雷达的中频信号处理工作。
