基于自適應(yīng)Chirplet分解的艦船目標(biāo)ISAR成像
The ISAR Imaging of Ship Based on Adaptive Chirplet Decomposition
-
摘要: 相對于飛機(jī)目標(biāo)的ISAR成像，艦船目標(biāo)的ISAR成像同樣具有重要意義, 但國內(nèi)對艦船目標(biāo)的成像研究剛剛開始。由于艦船運(yùn)動的復(fù)雜性，使得艦船目標(biāo)的成像條件要比飛機(jī)目標(biāo)復(fù)雜得多，傳統(tǒng)的針對飛機(jī)目標(biāo)的成像方法已經(jīng)不能滿足要求。因此，該文提出了基于自適應(yīng)Chirplet分解的艦船目標(biāo)成像方法，得到了艦船不同時刻的瞬態(tài)ISAR像。

Abstract: The ISAR imaging of ship is significant relative to plane. The imaging condition of ship is more complicated than plane due to the complexity of the ships movement, and the conventional ISAR imaging algorithm to the plane can not be satisfactory to the ship. So, a new method based on adaptive Chirplet decomposition is proposed here, the instantaneous ISAR ship image is obtained. -
