19315 1维综合孔径微波辐射计通常会采用G矩阵模型法来实现亮温图像的重建。 The G-matrix model method is usually used to achieve the brightness temperature reconstruction forthe one-Dimensional (1-D) synthetic aperture microwave radiometer system.
19316 对于1维辐射计系统，成像过程主要包含：辐射计仪器观测2维全视场的目标场景亮温，得到1维的可见度函数采样值，再通过对系统参数矩阵G求逆来实现目标场景的1维图像重建。 For the 1-D radiometer system,the imaging process mainly includes: the radiometer instrument observes the full field of view of the 2-D targetscene maps, and obtains the 1-D samples of the visibility, and then inverts the system parameter matrix G torealize the reconstruction of the 1-D image of the target scene.
19317 由于1维辐射计系统的采样基线只分布在空间频率域的1个维度上，所以在图像重建过程中，需要实现矩阵G从2维到1维的转换。 Since the system sampling baselines are onlydistributed in the 1-D of the spatial frequency domain, in the process of the brightness temperature imagereconstruction, the matrix G needs to realize 2-D to 1-D conversion.
19318 对此，该文提出了两种适用于1维综合孔径微波辐射计成像的G矩阵修正方法。 Therefore, two G-matrix modification methods are proposed to improve the imaging quality for the 1-D synthetic aperture microwave radiometer.
19319 并针对目前已经完成的8单元辐射计地面样机系统和目前正在研制的10单元盐度计样机系统，通过理论分析和仿真实验，验证了G矩阵修正法对1维综合孔径微波辐射计成像结果的改善效果，以及对天线方向图旁瓣恶化所引入成像误差的有效抑制。 For the 8-element ground radiometer prototype system and the 10-element salinity radiometer system, theoretical analysis and simulation experiments have verified that the G-matrix modification methods proposed in this paper can effectively improve the imaging results, and can effectively suppress the imaging error caused by the side-lobed degradation of the antenna patterns.
19320 为提高电子战中弹载雷达检测性能，该文提出基于纳什均衡的雷达波形设计方法。 In order to improve missile-borne radar detection performance in modern electronic warfare, a radar waveform design method based on Nash equilibrium is proposed.
19321 首先建立电子战条件下雷达与干扰信号博弈模型，基于最大化信干噪比(SINR)准则，分别设计了雷达和干扰的波形策略； Firstly, the radar and jammer game signalmodels are established in electronic warfare. Based on maximum Signal-to-Interference-plus-Noise Ratio(SINR), waveform strategies of radar and jammer are designed respectively.
19322 然后通过数学推导论证了博弈纳什均衡解的存在性，设计了一种重复剔除严格劣势的多次迭代注水方法来实现纳什均衡； Secondly, the existence of Nashequilibrium solution is demonstrated by mathematical derivation and verified in experimental simulation. Amultiple iterative water-filling method which repeatedly eliminates strict disadvantages is designed to achieveNash equilibrium.
19323 通过二步注水法推导了非均衡的maxmin优化方案； The maxmin scheme of disequilibrium game is deduced by two-step water-filling method.
19324 最后通过仿真实验测试不同策略下雷达检测性能。 Finally, the radar detection performance of optimization strategies is tested by simulation experiments.
