连续波信号 meaning in Chinese
continuous wave signal
continuous-wave information
Examples
- For it has many unique advantages , pseudo - noise linear m - sequence binary phased coded cw signal is widely used in the new generation air defense systems
伪随机m序列相位编码连续波信号体制由于其固有的优点,在新一代地空制导雷达中得到了广泛的应用。 - 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。 - First in this paper , we review the development of radar signal processing and cfar detector , analyse the structure and principle of the signal processor , ca - cfar and os - cfar detectors . then , in view of the characteristic of prc cw signal , analyses the statistics characteristic of scattering bodies , models of target , noise , ground - clutter and weather - clutter are made . these lay a theoretic foundation of signal processing and cfar detector
然后,本文针对x波段伪随机m序列相位编码连续波信号体制,分析了各种散射体的统计特性,对雷达目标及检测背景噪声(热噪声、地杂波和气象杂波)进行了理论分析和统计检验,建立了目标及检测背景的目标模型,确立了信号处理和恒虚警检测的理论基础。 - Based on the features of modulate - wave and unmodulate - wave , different methods being suitable for these two kinds signals is respectively discussed by theory and simulation . the result of simulation can be used in the practice . in this chapter , the research about the tdoa extraction method of the unmodulate - wave is also the relevant technologies needed to be study in the " life detection and orientation of earthquake emergency response system "
