差拍信号 meaning in English

beat signal
beatsignal

The main research work and results can be summarized as follows : 1 . analysis of echo signal of lfmcw radar , including beat signal of single - target and multi - target . 2
本文的主要工作包括:对lfmcw雷达回波信号(单目标差拍信号和多目标差拍信号)进行了分析;对lfmcw雷达模糊函数进行了分析。
The method first realizes detection and classification of moving targets with different ambiguous velocities via mtd in order to simplify the spectrum of beat signal , and then eliminates moving targets " range - velocity coupling with frequency domain pairing
该方法首先通过mtd实现对不同模糊速度目标的检测和分类，简化差拍信号频谱环境，然后利用频域配对法实现动目标的距离速度去耦。
In this thesis a high precision frequency ( range ) estimation technique based on the phase of the fft of the beat - note signal is presented . the phase of the fft of the beat - note signal changes with the range between the radar and the liquid surface
差拍信号的fft幅度最大处的相位随距离变化，因此可以利用fft相位在一个频率(距离)分辨单元范围内估计差拍信号的频率(距离)的位置，从而提高频率(距离)估计精度。
