  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成像及干涉技術應用研究一因此直接無法分辨目標的架數,我們借鑒isar的技術,通過較長時間的相干積累,在多普勒頻域上對目標進行分辨。而對于目標,可分為近似剛性的多目標和非剛性的多目標,所以對于可以近似為剛體的目標相對固定,運動方式一致,可以近似看作一個大目標,採用最小墑準則對平動相的進行補償,但是大多數並不滿足剛體近似的目標,由於目標在相干積累時間的多普勒頻率近似呈線性變化,通過對較短數據利用relax的時頻分析方法,提高了頻率域上目標分辨的性能。由於橫向解析度取塊于橫向積累時間,所以利用radnwigner變換得到瞬時的一維橫向距離像大大提高了對目標的分辨,對模擬和實測數據的大量分析結果表明此方法的有效性和可行。
  2. Then, author introduces geometric nonlinear analysis theory, geometric nonlinear calculation theory during construction period, load position of live load considering geometric nonlinear and calculation theory of worst - case value, static time history theory for vehicle running, geometric nonlinear analysis theory of natural vibration and structural dynamic reaction and so on. all of these theories fit any appointed structure with corresponding programs. so a series of completed analysis approaches that cover all geometric nonlinear factors of bridge structure are formed
