18915 基于不同SAR工作体制，在不同海况下进行了理论近似仿真，并进行了干涉SAR全链路仿真，全链路仿真结果能够与理论仿真较好地吻合，验证了误差模型的正确。 The error models in different SAR modes under various sea states are simulated. The error model is validated by the interferometric SAR full-link experimental simulation and the simulation results are consistent with the theoretical values.
18916 结果显示由海浪引起的误差随着多普勒中心频率近似呈线性变化，且与目标散射加权径向速度成正比。 The results show that the errors are approximately linear changing with the Dopplercentroid frequency and are proportional to the radial velocity of targets modulated by scattering.
18917 误差不仅与海浪特性相关，还与雷达系统参数相关，这能为未来系统设计、误差预算和海面高程处理提供参考。 The errors are not only related to the characteristics of the waves, but also related to system parameters. This work can provide the feasible suggestions for future system design, error budget and data processing.
18918 为提高全变分图像降噪模型的降噪性能和边缘保持性能，该文提出一种曲率差分驱动的极小曲面滤波器。 To improve performance of denoising and edge preservation of the total variational image denoising model, a curvature difference driven minimal surface filter is proposed.
18919 首先，在平均曲率滤波器模型基础上，引入自适应曲率差分边缘探测函数，建立曲率差分驱动的极小曲面滤波器模型； Firstly, the presented filter model isconstructed by adding an adaptive edge detection function of curvature difference to the mean curvature filtermodel.
18920 接着，从微分几何理论角度，阐述该能量泛函模型的物理意义和平均曲率能量减小方法； After that, from the perspective of differential geometry theory, the physical meaning of the energy functional model and the method of reducing the average curvature energy are elaborated.
18921 最后，在离散的图像域，通过迭代的方式使图像每个像素邻域内的曲面向极小曲面迭代进化，实现能量泛函的平均曲率能量极小化，从而能量泛函的总能量也完成极小化。 Finally, in the discrete image domain, the surface in the neighborhood of each pixel of the image is iteratively evolved to the minimal surface to minimize the average curvature energy of the energy functional, so that the total energy of the energy functional is also minimized.
18922 实验表明，该滤波器不仅能去除高斯噪声、椒盐噪声，还能去除这两类噪声构成的混合噪声，其降噪性能和边缘保持性能优于同类型的其他5种全变分算法。 Experiments show that the filter can not only remove Gauss noise andsalt and pepper noise, but also remove the mixed noise composed of these two kinds of noise. Its performance of noise reduction and edge preservation is better than the other five total variational algorithms of the same kind.
18923 穿墙场景下，由于墙体造成信号严重衰减，接收信号中目标反射信号的能量大幅下降，接收信号淹没在收发机直射信号和室内家具反射信号中，难以检测墙后目标。 In through-the-wall scene, due to the serious attenuation of signal caused by wall, the energy of target reflection signal in the received signal decreases significantly and the received signal is submerged in the direct signal of the transceiver and the reflection signal of indoor furniture, making the target behind wall is hard to be detected.
18924 针对上述问题，该文提出一种新颖的基于多维信号特征融合的穿墙多人体目标检测算法(TWMD)。 In view of the above problems, a novel Through-the-Wall Multiple human targetsDetection (TWMD) algorithm based on multidimensional signal features fusion is proposed.
