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。The obtained results do not support a major gene for body mass index in chinese, the discrepancies between our study and previous studies may result from ethnic difference between chinese and other populations ; the general model provides the best fit to the data, while the environmental model is the second parsimonious model, perhaps due to complex mode of body mass index inheritance ; a moderate heritability estimate is found for body mass index ( h2 = 0. 313 ), lower than that of other populations, this is presumably due to the fact that aside from the influence of genetic bases, body mass index is strongly influenced by environmental factors and that there is a low proportion of obese individuals in samples ( only 4. 1 % individuals have body mass index > 30 )
