- 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。 - From analysis , we are able to come to the conclusion that real estate tax in china owns functions such as stabilizing revenue sources , equalizing burdens , shortening gaps , lever regulation and promoting economic development etc . as far as a complete real estate project is concerned , presently , in china , real estate tax and other relevant taxes include the thirteen kinds of taxes
从而分析得出,我国房地产税收应有提供稳定的税收来源,平等负担、缩小差距,杠杆调节、发展经济等职能。房地产具有位置固定性、增值保值性等特殊的资产属性,而且房地产作为不动产,具有难以隐匿的特点,是一种比较稳定的税收来源。 - You may get them on the inside of your lips and your cheeks , around gums and on the tip of your tongue . they may sometimes have a yellowish white coating . around them it is swollen and red . in the more severe situation , you will have a headache , feel dizzy and get bad - tempered easily it is better for people to take longdan xiegan decotion . cankers sore of blood - stasis
溃疡面色泽呈淡灰白色，有发展快愈合慢之特点，女性往往在月经前及月经期间口腔粘膜中突然发生数枚溃疡，局部剧烈疼痛，头痛位置固定不变，月经色呈紫黯，有淤斑，如长期不治，易导致病情加重。 - At present , most actuating mechanism only can transmission one kind of movement , but there are some of them need to transmission continuous and long distance round about movement . so we brought forth a new kind of actuating mechanism , that is the drumshaped gear with ring - involute teeth mechanism . we can also named dimensional gear mechanism
现代的机械装置提出了实现连续的空间曲线啮合传动要求,例如爬楼机械装置的传动机构就是如此,而现有的齿轮传动机构大多只能实现两轴之间相对位置固定的运动和动力的传动,在实际的运动中经常需要传递两轴之间相对位置不断变化的随机运动。
