| 1. | In addition to rainfall intensity , the radar also detects the speed of movement of raindrops using the doppler principle
因此这台雷达除可探测降雨强度外，还可利用多普勒原理来探测雨点的移动速度。 |
| 2. | Using the doppler principle , low level winds are determined from the speed and direction of the movement of the eddies
运用多普勒原理，低层大气的风向和风速可从上述湍涡的移动方向和速度计算出来。 |
| 3. | In addition to measuring rainfall intensity , the doppler radar detects the speed of movement of raindrops based on the doppler principle
故此，这台多普勒雷达除可探测降雨强度外，还可利用多普勒原理来探测雨点的移动速度。 |
| 4. | The doppler principle can be explained by noting the change in pitch of an ambulance siren . the pitch heightens as the ambulance approaches and lowers as it departs
多普勒原理可利用救护车响号的声调转变来解释：当救护车走近时，声调会升高远离时，声调会降低。 |
| 5. | The doppler principle can be explained by noting the change in pitch of an ambulance siren . the pitch heightens as the ambulance approaches and lowers as it departs
多普勒原理可利用救护车响号的声调转变来解释：当救护车走近时，声调会升高；远离时，声调会降低。 |
| 6. | The doppler principle can be explained by noting the change in pitch of the siren on a passing ambulance . the pitch heightens as the ambulance approaches and lowers as it departs
所谓多普勒原理，可通过救护车响号的声调转变来解释：当救护车走近时，响号的声调会升高远离时，声调则降低。 |
| 7. | If the star emitting the light is moving away from us , its light rays have a longer wavelength ( lower frequency ) by virtue of doppler principle and this is manifested in a general shift of the spectrum lines towards the red end of the spectrum
如果发某种光的恒星离开我们，根据多普勒原理，其光线的波长较长（即频率较低） ，在光谱上则显示出谱线全部移向红端。 |
| 8. | In the preface to this dissertation , the development of the isar is introduced briefly . subsequently the range - doppler principle and many kinds of methods for motion compensation are detailed . finally , the main contents of this thesis are summarized
本文的第一章为绪论,首先简要介绍了isar的国内外研究进展,然后阐述了距离-多普勒成像原理和isar运动补偿的多种方法,最后概述了全文的主要内容。 |
