SARReturnWaveSignal
基于FFT的快速SAR分布目标回波模拟算法.
大面积分布目标的合成孔径雷达(SAR)回波模拟需要大量的运算，文中提出了一种合成孔径雷达回波模拟的快速算法，算法利用时域插值和FFTl’来缩减运算量，对于大面积目标回波模拟时，该算法有很高的效率。文中详细分析sinc函数插值所带来的误差以及补偿方法，并在次基础上提出了一种利用增采样插值方法，该方法以增加少量运算为代价，使得模拟精度的大幅度提高。文中比较了传统方法和基于FFTl’的快速SAR分布目标回波模拟算法的模拟结果，证明了这种快速算法确实行之有效。(The simulation of distributed targets is very important to the design of synthetic aperture radar(SAR)sys-
tems．Since the end product is SAR images，the echo of SAR signals needs to be simulated and then processed form SAR images，an d the parameters needs to be measured and the perform ance of the images should be，an d then evaluated．The designing parameters of SAR could be adjusted to meet the requirement of users before developing SAR systems，specially
in space—bome SAR systems．Th e simulation data is also needed during the developing an d debugging of a space—borne SAR real—time processor．Another purpose of simulation is to supply a great deal of simulation imag es to train image usors of space—bo rne SAR before it launch．)

电力系统暂态故障模拟再现系统
说明： 提出并研制了一种新型电力系统暂态故障模拟再现系统。该系统通过将系统发生故障时故障录波器录下的数据转换为符合IEEE的COMTRADE格式文件，经数据处理软件进行分析后由电脑并口送入多功能继电保护测试仪，最终由测试仪还原成故障时的ＰＴ、ＣＴ二次侧电压、电流信号。该系统对继电保护装置参数整定、事故原因查找及分析等有辅助作用。(proposed and developed a new type of power system transient fault simulation and reconstruction system.IEEECOMTRADE.
