| 1. | Doppler-sonar is a dead-reckoning system .
多普勒-声纳是一种推测航位系统。 |
| 2. | The doppler frequency is a function of the two scattering directions .
多普勒频率是两个散射方向的函数。 |
| 3. | The doppler frequency can be obtained as a heterodyne or beat effect .
由于外差或频差效应，能够得到多普勒频率。 |
| 4. | For example, dopple radar, airspeed, waterspeed, or some form of ground-based aids might be used .
例如，可以采用多普勒雷达、空速、水速、或者由地面基地提供的某种形式的信息。 |
| 5. | This is found by observing the doppler shift in the frequency of the radio signals broadcast from the satellite .
这是通过观测卫星所发射的无线电信号频率中多普勒偏移来确定的。 |
| 6. | Moreover, since the atoms are in random thermal motion the frequency spectrum will be altered by the doppler effect .
而且，由于原子是在作无规则热运动，多普勒效应也会使频谱发生改变。 |
