observed object
sighting target
Examples
- Sar has the whole weather and the whole day characteristics that observing two dimensions high resolution image of the object , now which has widely been applied in many fields
由于它具有全天候、全天时观测目标的二维高分辨图像的突出优点,所以在许多方面都获得了广泛应用。 - To test which was correct , astronomers led by douglas clowe of the university of arizona turned their telescopes on the cloud in the bullet cluster
由美国亚里桑那大学的道格拉斯?克洛韦领导的一批天文学家将望远镜的观测目标对准了子弹状星云团中的气团，以检验上述两个理论的正误。 - Such high resolution enables it to overcome the problems of source confusion . soon after the launch in 1999 , chandra provides us fruitful results ; one of the major targets is m31
钱德拉天文台于1999年发射后，在短短6个月内已取得不少重要成果，而它其中一个重点观测目标便是m 31 。 - Among the different imaging algorithms , the range - doppler fft ( r - d fft ) algorithm , based on range - doppler theory , in which the fast fourier transform ( fft ) is employed to reduce compute burden , is widely used in various imaging radar because it can be easily realized in real - time application
陆基成像雷达( gbr )作为isar成像技术的重要应用,其观测目标具有速度快,惯性大,运动相对平稳等特点,针对这些特点,本文对isar成像运动补偿方面作了较为深入的研究。 - Frequency code is not uniformity distribution and keeps to a probability distribution function defined by the spectral characteristics of the target of interest . the phase code is equally duality pseudo - random sequence and used to reduced the sidelobes of the signal correlation function . and the mismatch - phase sequence is corresponding with the frequency sequence one by one
而频率编码为不均匀分布，由所观测目标的频谱信息提取出概率密度函数决定频率编码序列的分布；相位编码为二元的伪随机序列，采取均匀的二相编码，消减同频脉冲带来的过高的相关函数的旁瓣；而失配相位为与频率编码相一一对应于各子脉冲中。
