摘要按照生物样品分辨单元具有多种透过率的特点，设计了一个多衬度的台阶状蛋白质模型，根据曝光量与衬度，信噪比，抗蚀膜性能的关系，确定了曝光量。 - Simulation results obtained using data and real data show that this method is effective . ^ for the active low - resolution radar , its longitudinal resolution usually is more than one hundred meters and as high as several hundred meters
针对现役的低分辩雷达，它的纵向分辨率通常达一百米甚至数百米对于编队飞行的目标，由于目标的间距和方位张角都小于低分辨雷达的可分辨单元， - In this paper a maneuver target detection method based on acceleration compensation is proposed to solve the problem mentioned above . with the ability to refocus return target signal energy to a single doppler cell , this method can gain a better maneuver target detection ability
针对上述问题本文提出了一种基于加速度补偿的机动目标检测方法,该方法能够将目标回波能量重新聚集到一个多普勒分辨单元内。 - In this thesis a high precision frequency ( range ) estimation technique based on the phase of the fft of the beat - note signal is presented . the phase of the fft of the beat - note signal changes with the range between the radar and the liquid surface
差拍信号的fft幅度最大处的相位随距离变化，因此可以利用fft相位在一个频率(距离)分辨单元范围内估计差拍信号的频率(距离)的位置，从而提高频率(距离)估计精度。 - Terrain slope information can be drawn from polarimetric synthetic aperture radar ( sar ) two - dimensional image , so that three - dimensional image can be generated . it differs from two - pass or repeated trace insar that uses interference phase method to obtain topography height . the p - sar three - dimensional image technology uses the stokes matrix formed by two - dimensional images resolution cells , then applying polarimetric synthesize to stokes matrix can produce polarization signature of the scatter cross - section a - ( , x ) for any ( ellipticity ) and ( orientation ) polarization state
这种方法不同于重复轨道和双通道insar系统，不是利用干涉法提取高度信息，而是利用极化sar二维图像各分辨单元的stokes矩阵，通过极化综合估计每个分辨单元的共极化散射特性和交叉极化散射特性(极化指纹) ，以及共极化散射特性最大值时对应的极化椭圆度x利极化椭圆方向角，求解地形的高度轮廓。
