  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編隊目標的架數，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。而對于編隊目標，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編隊目標相對位置固定，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位的進行補償，但是大多數並不滿足剛體近似的編隊目標，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編隊目標的分辨，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. Because of the original design standard was low, the horizontal angur rigidity is serious lack, when the high speed train passes, the exceed limit of the horizontal swing had affected the lifting of the main trunk line, these diseases had been existed earlier but had not been gotten to resolve radical, and along with the increasing in speed of railroad train, these diseases performance will be more seriously, it ' s time for resolve

    同時提速列車對橋梁結構的動力作用增大，特別是對上承式鋼板梁。由於原設計標準低，橫向剛度嚴重不足，高速列車通過時橫向擺動嚴重超限等已嚴重影響了主要干線的提速，這些病害很早就存在但沒有得到根治，隨著列車提速，這些病害表現越來越嚴重，已到了必須整治的時候了。
  3. Cross lines timer

  4. Above all, with the data acquired by tests, this thesis has analysized the lateral resistanc, longitudinal resistance and rail creep etc between ballast and sleeper before and after mass machine work, discussed the effect of mass machine on stability of continuously welded rail track, reseached the change regularity of fastening - down temperature of rail, which is resulted by mass machine work, and have settled the suitable range of work temperature which guarantees the stability of jointless railway. what ' s more, this thesis has put forward the appropriate work pattern, work temperature and work area for mass machine work in future. at the same time, this thesis has given rational suggestions about some conditions worth of attention in production of mass machine, which can in return raise the work productiveness of mass machine. at last, this thesis has considered formulating reasonable measures for operation organization and work standard, so that mass machine work can play an important role in maintenance, which can reduce work load, raise work efficiency and maintenance cost in daily maintenance

    本文通過實測的各種數據，分別對大機作業前後道床對軌枕的橫向阻力、縱向阻力、鋼軌爬行情況等進行深入分析，進一步探討大機作業對無縫線路穩定性的影響，研究大機作業引起的鎖定軌溫的變化規律，確定保證無縫線路穩定的合適作業軌溫范圍。為我國今後的大型養路機械作業提出合理的作業方式、合適的作業軌溫和作業地段，同時對大型養路機械作業中應注意的問題提出合理化建議，為大型養路機械作業提供更高的安全保障，進一步提高大機作業效率。最後，對工務段在大機作業中的配合制定完善的施工組織措施及作業標準，使大機作業在養護維修中發揮更大的作用，為工務段日常的養護維修減少工作量，提高勞動效率，降低維修成本。
