可再生能源光伏发电和风力发电是重要的能源,而外界环境的影响也要分析,提出的方案很好地适应了这种变化。(The integration of renewable resources such as solar and wind energy is becoming increasingly attractive.
This is being used widely for bstitution of oil-produced energy and will help to minimize atmospheric
degradation.)

介绍了经典的时频分布和检测理论的同时,作者利用时频分布的方法,将一
维时间信号转化到二维的时频空间中,通过提取图像的特征来判决信号和杂波,
采用的数据是使用McMaster IPIX雷达,在加拿大东海岸附近测得的。实测数据
研究表明此方法可以得到很好的检测结果。
(In this paper,we first review the time-frequency analysis and time
-frequency-based detection methods.Secondly,by analyzing a mass of the measured
data of sea clutter,we show the difference of time-frequency geometric features
between echoes with a target and pure sea clutter.Finally,we given the detection
algorithm based on the time-frequency geometric features.The results of the measured
data show that the proposed method can effectively find low-velocity small targets in
sea clutter.This approach is a novel try to detect small targets in sea clutter.)

求。其仿真算法对于实现数字化控制变频调速系统具有一定的价值。
(To provide the necessary design parameters for the actual motor control system, the modeling course of
voltage space vector pulse wide modulation(SVPWM)agrithmetic and AC motor under Matlab/Simulink environment
are introduced. The dynamic model of variable frequency speed regulating system based on vector control is
discussed according to the principle of SVPWM. The new method of realizing simulation, key problems and
results of the simulation are analyzed in detail. The experimental simulation results show that this system has
smaller fluctuations of voltage and torque, quicker response speed, and all of the indicators accord with the
performance of the actual motor. The simulation agrithmetic have value to realize controlling motor with digital
signal processing.
