- Example Sentences:
| 1. | Due to the short distance among the planes which fly in a group , the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image , we may separate them , but a long time of coherent processing is needed < , for the formation targets , it can be approximately divided to rigid body and nonrigid body , so for the formation targets , that can be regarded as rigid which has a relative position and an identical movement , can be approximately considered as a large target , and be compensated by translational phase with the rule of minimum entropy , but for the most those cannot accord with the approximation of rigid , being the doppler - frequency of the aim is linear changed , by the relax method with short data , increases the resolving performance of multiple target to the aim in the frequency domain , since cross - range resolution is based on the accumulative time , so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation
低分辨isan成像及干涉技术应用研究一因此直接无法分辨编队目标的架数，我们借鉴isar的技术，通过较长时间的相干积累，在多普勒频域上对目标进行分辨。而对于编队目标，可分为近似刚性的多目标和非刚性的多目标，所以对于可以近似为刚体的编队目标相对位置固定，运动方式一致，可以近似看作一个大目标，采用最小墒准则对平动相位的进行补偿，但是大多数并不满足刚体近似的编队目标，由于目标在相干积累时间的多普勒频率近似呈线性变化，通过对较短数据利用relax的时频分析方法，提高了频率域上目标分辨的性能。由于横向分辨率取块于横向积累时间，所以利用radnwigner变换得到瞬时的一维横向距离像大大提高了对编队目标的分辨，对仿真和实测数据的大量分析结果表明此方法的有效性和可行。 | | 2. | In this paper , the concept of acceleration ambiguity function ( aaf ) and acceleration resolution is put forward for the first time . using aaf , the effects of target ' s relative acceleration on several outputs of a linear - phase matched filter are analyzed , such as the output signal - noise - ratio loss , the doppler resolution , the constraint on optimal accumulative time ( opt ) and their tolerable limits
论文首次提出并研究了加速度模糊函数和加速度分辨力的有关概念，并以加速度模糊函数为分析工具，详细讨论了加速度对线性相位匹配滤波器的输出信噪比的损失程度、对多卜勒频率分辨能力的影响程度、对最优相参积累时间的约束关系以及线性相位匹配滤波器输出受加速度影响的容限等问题。 | | 3. | Of the individual annuities that get more or less to depend on individual capture expends more or less to mix the accident that accumulates time ; 3 it is rural soil , be in business etc of all kinds execute unified social endowment insurance from personnel of course of study system , the flow of facilitating country labor ; 4 it is to adopt the working method that governmental organization guides and the farmer combines of one ' s own accord
