  2. 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分辨編隊目標的架數,我們借鑒isar的技術,通過較間的相干積累,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的頻分析方,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間,所以利用radnwigner變換得到瞬的一維橫向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的有效性和可行。

    盡管國內外經濟和人口學方面的專家與學者很早就開始了對農村勞動力問題的研究並取得了極大的進展,但是,我國在研究農村勞動力問題,基於三點:其一,我國國情決定了國外的理論例如劉易斯理論,雖然對研究我國的農村勞動力問題具有指導意義,但卻不能照搬這些理論;其二,從國內看,我國對該問題的研究重視定性分析而定量分析明顯不足;其三,缺乏對我國占國土面積69 、人口56的山區農村這一特殊區域內的勞動力開發利用及轉移的專門性研究。為了彌補這三個缺憾,論文採用經濟計量學的數量分析方,利用實際調查資料,藉助tsp軟體,建立了以外出勞動力數量為被解釋變量,城市化率、農村產業結構、城鄉收入差、農村社會基礎設施建設、農村勞動力素質以及人口自然增率六個變量為解釋變量的模型,通過對該模型進行經濟學、統計學、經濟計量學三個方面的檢驗,得出如下結果:城鄉收入差和城市化率是影響山區農村勞動力開發利用及轉移的最重要的兩個因素;農村社會基礎設施建設和農村勞動力素質是較為重要的兩個影響因素;而農村產業結構和人口自然增率相對來說是較不顯著的影響因素。據此,本文提出了在研究山區農村勞動力開發利用及轉移問題,應慎重對待城鄉收入差、城市化水平、農村勞動力素質、農村產業結構、農業機械化五個問題。
