最小均方（LMS）自适应算法就是一中已期望响应和滤波输出信号之间误差的均方值最小为准的，依据输入信号在迭代过程中估计梯度矢量，并更新权系数以达到最优的自适应迭代算法。LMS算法是一种梯度最速下降方法，其显著的特点是它的简单性。这算法不需要计算相应的相关函数，也不需要进行矩阵运算。(Minimum mean-square (LMS) adaptive algorithm is that one has to respond to the expectations and filtering the output signal of the mean square error between the value of the minimum-based, based on the input signal is estimated in the iterative process of gradient vector, and to update the weights in order to achieve the most Adaptive iterative algorithm gifted. LMS algorithm is a steepest descent gradient method, and its significant features is its simplicity. This algorithm does not require calculation of the corresponding correlation function, nor the need for matrix calculation.)

运动目标模拟器相参性分析，分析了基于数字射频存储器(DRFM)的运动目标模拟器(MTS)相参性。由于DRFM延时的离散性,引起了MTS输出信号相位的改变,破坏了信号的相参性,使MTS输出信号频谱发生变化,不仅使谱线位置移动,而且还产生了附加的寄生谱线。分析结果表明,延时更新率(Fc)决定了谱线间隔,并通过sinc函数决定谱线的幅度,而雷达信号频率与所模拟目标的速度共同决定谱线的移动。 (Moving Target Simulator Coherent Analysis, Moving Target Simulator (MTS)-based digital radio frequency memory (DRFM) coherent. Due to the the DRFM delay discrete MTS output signal of the phase change is caused, the destruction of the phase of the signal parameters, the MTS output signal spectrum changes, not only the spectral line position, but also generates additional parasitic spectral line. The analysis results show that the delay update rate (Fc) determines the spectral interval by sinc function determines the amplitude of the spectrum, while the radar signal frequency and speed together determine the movement of the spectral lines of the simulated target.)

逆变器具有灵活、高效的特点，是新能源并网的主要接口。当多个逆变器连接到电网的同一个公共连接点时，逆变器非理想的电源特性，使得逆变器之间、逆变器与电网之间存在的谐波交互作用可能引发谐振， 使系统出现过电压、 过电流现象影响电网的电能质量，甚至威胁系统的安全稳定运行(Inverter is flexible and efficient, and it is the main interface of new energy integration. When multiple inverters are connected to the same common connection point of the power grid, the inverter is not ideal. The harmonic interaction between the inverters, the inverter and the grid may cause resonance, which causes the overvoltage and overcurrent to affect the power quality of the power grid and even threatens the safety of the system. stable operation)
