Abstract : a simulation method is proposed to predict the motion artifacts of plasma display panels ( pdps ) . the method simulates the behavior of the human vision system when perceiving moving objects . the simulation is based on the measured temporal light properties of the display for each gray level and each phosphor . both the effect of subfield arrangement and phosphor decay are involved . a novel algorithm is proposed to improve the calculation speed . the simulation model manages to predict the appearance of the motion image perceived by a human with a still image . the results are validated by a set of perceptual evaluation experiments . this rapid and accurate prediction of motion artifacts enables objective characterization of the pdp performance in this aspect 文摘:针对目前等离子显示屏普遍存在的运动伪像问题,提出了一种新颖的模拟计算方法,该方法实现了对等离子体显示屏运动伪像的准确、快速估计.该方法通过测量等离子显示屏不同颜色不同灰度下光信号随时间的变化情况,仿真人眼对运动图像的视觉感知行为,模拟计算出任意图像以一定速度运动下的视觉感知效果.新算法不但加入了等离子显示屏荧光粉的延迟效应的影响,而且提高了模拟计算速度.所得模拟结果与实际主观视觉感知实验相符.这种快速准确的估计使对等离子显示器件运动伪像的客观评价成为可能
It combines the real echoes with the date simulated using the real airborne sar system parameters to analyze and validate the method . after the combined data are filtered , the improved greatest of cell - average constant - false - alarm - rate ( go - ca - cfar ) is used to judge whether moving target is detected or not . in the following , real moving target is detected and its velocity and position is gained through which it is focused well 将接收的实际场景数据与实际系统参数下模拟的典型数据相结合，分析、验证了频域滤波法的性能，并对滤波后的数据采用改进的选大单元平均恒虚警率( go - ca - cfar )方法进行处理，判断动目标是否存在；然后对实际的动目标进行检测，准确的估计出目标速度及位置并对目标重新聚焦成像，接下来将聚焦的动目标图像和常规sar图像迭加，同时得到了回到真实位置的动目标聚焦图像和实际场景sar图像。
Firstly , the square sum of estimate error is only half of it " s original square sum of measurement data , the precision of result is highly enhanced . secondly , the precise estimate data takes place of bad data . thirdly , this method estimate some data that the power system needs but the measure system do not give 从估计结果来看，一是在不良数据不计在内的情况下，估计值的误差平方和仅是原始测量数据误差平方和的一半左右，在准确性上有较大的提高；二是用准确的估计值代替了不良数据；三是准确地估计出了一部分电网调度工作需要，而又没有进行测量传送的数据。
