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。Using the combinatorial method of constructibility and the technique of exchanging colors, we present the best upper bounds of dynamic chromatic number of halin graphs and sp graphs, and determine the dynamic chromatic number of a type of sp graphs, we determine the incidence chromatic number of some descartes product graphs and some join graphs. at last we determine the entire coloring number of 1 - tree and prove a conjecture of edge - face coloring
