symmetrical pulse meaning in Chinese
对称脉冲
Examples
- The application of multiple digital phase - locked technology and the high frequency complementary symmetrical pulse technology is the key content discussed in the paper
多重数字锁相技术在同步环节中的应用和本相高频互补对称脉冲技术在脉冲触发中的应用，是本文探讨的核心内容。 - The pseudorandom codes have a good autocorrelation of double - values . in recent years , to solve the problems of anti - interference and the ambiguity of range and velocity , a lot of countries do much research to change the waveform of radar signal . the most important improve is to use symmetrical pulses to interrupt frequency modulated continuous wave ( fmpcw )
早期的fmicw采用伪码序列截断,伪随机码具有良好的双值自相关特性,其中最常用的是m序列截断的fmicw 。近年来,为了解决抗干扰和测距、测速模糊问题,许多国家已对雷达信号波形的改进进行了研究。 - Based on the analysis of the beat frequency signal , the expression of the beat frequency phase is deduced . the expression indicates physics meanings of quantities to be detected and supplies theoretical bases for detection methods . by using two - dimensional fft , the range and velocity information of target is got out from the echo . according to the periodicity range ambiguity of symmetrical pulses in fmpcw , the processing method of sliding time window is used
通过对差频信号进行的分析,得出了差频相位的具体表达式,表现出了要检测的各量的物理意义,对检测的方法提供了理论依据。利用二维fft方法,可以有效地提取回波中目标的距离与速度信息。对于fmpcw信号由于均匀脉冲产生的周期性距离模糊的问题,采取时间波门的处理方法。
