log-FDA transmit beamforming
阵元间频率增量按对数增加,发射波束不再按距离周期性出现,发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列,log-FDA能够抗距离相关的干扰,而且发射能量不泄露,具有一定的低截获性能。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)

backstepping
说明: 针对带储能的光伏系统出力不稳定问题,基于储能变流器提出了一种带有灰色补偿的Back-stepping控制方法,以实现对并网点上层规划层面有功功率P和无功功率Q指令的跟踪控制,同时保证并网点电压的 稳定。(Aiming at the problem of output instability of photovoltaic system with energy storage, a back stepping control method with gray compensation is proposed based on energy storage converter to realize the tracking control of active power P and reactive power Q command at the upper planning level of the parallel network, and to ensure the stability of the voltage of the parallel network.)

chapter5attitude
说明: 卫星姿态是指卫星星体在轨道上运行所处的空间指向状态。将直角坐标系的原点置于星体上,指向地面的Z轴反映偏航方向,Y轴反映俯仰方向,X轴反映滚动方向。星体在高空中沿局部地球铅垂方向和轨道矢量方向运行,不时地产生对三轴的偏移。姿态控制是通过姿态控制分系统(ACS)来实现,使用地平扫描仪可感应俯仰和滚动轴的姿态误差,使用速度陀螺仪和罗盘可感应偏航轴的姿态误差。(Satellite attitude refers to the spatial orientation of a satellite in orbit. The origin of the Cartesian coordinate system is placed on the star, the Z axis pointing to the ground reflects the yaw direction, the Y axis reflects the pitching direction, and the X axis reflects the rolling direction. The stars move along the direction of the earth's vertical direction and the orbit vector in the high altitude, resulting in the deviation of the three axis from time to time. Attitude control is realized by attitude control subsystem (ACS). The attitude error of pitch and rolling axis can be induced by using horizon scanner, and the attitude error of yaw axis can be induced by using speed gyroscope and compass.)
