Example Sentences:

	1.	Unlike the range - doppler imaging in isar , this velocity transformation uses fft without the motion compensation . so the isar signal processing may not be applied directly 多普勒原理相比,主要区别是速度谱变换直接采用快速傅里叶变换,而没有isar的运动补偿处理。
	2.	First , the range - velocity transformation and the target detection are finished , and estimate the range , velocity and azimuth of the detected targets for target tracking 故必须先依据高频雷达信号处理流程完成对二维距离?速度谱变换以及对目标的检测、参量估值和航迹建立。
	3.	Second , based on the estimation , the fine dbf is performed and the target spectra are filtered . finally , the inverse velocity transformation and reverse weighting are done , and enough batches of signal are united 然后,根据参量估值结果,进行精细的数字波束形成,滤出目标谱线,做速度谱反变换并合并多批数据,得到待处理的方位向信号。
	4.	Because of the presence of the first - order sea echoes with dominant amplitude , the doppler resolution technique which based on the range - velocity transformation is needed to extract the targets information in hf radar 高频雷达工作在拥挤的短波波段,由于绝对占优的一阶海浪回波的存在,必须采用基于距离?速度谱变换的多普勒频率分辨技术来处理杂波,以提取目标信息。
	5.	The differences between this method and other similar methods are : ( 1 ) the fast synthetic source record algorithm based on the wave theory is adopted in prestack depth migration . ( 2 ) the plane wave source is used in migration that is consistent with the velocity analysis method . ( 3 ) by using the controlled illumination , the distortion of the plane wave source wavefield due to the lateral velocity variation is avoided therefore the error of velocity analysis is reduced and ( 4 ) the practical velocity spectrum makes the interactive migration velocity analysis feasible and convenient 与其他类似偏移速度分析方法的不同点在于： ( 1 )叠前深度偏移采用基于波动理论的快速合成震源记录算法； ( 2 )偏移方法采用平面波震源，与速度分析方法一致； ( 3 )应用控制照明技术，避免了因横向变速而导致的平面波震源波场在传播过程中的畸变，从而减小了速度分析的误差； ( 4 )实用的速度谱设计，使交互偏移速度分析可行且易于操作。
	6.
