恒虚警率 meaning in Chinese
constant false alarm rate
constant false-alarm rate
Examples
- A new conclusion in ca - cfar detection
单元平均恒虚警率检测中的一个新结论 - Cfar target detection in sar imagery
合成孔径雷达图像的恒虚警率目标检测 - Secondly , we systematically study the cfar target detection algorithm with the guide of the conclusion gained from the research of the clutter statistical models
其次,在研究杂波统计模型得到的结论的指导下,系统研究了恒虚警率( cfar )目标检测算法。 - ( 3 ) cfar method : according to earth clutter ' s character , i adopt cell average constant false alert rate ( ca - cfar ) and biparameter cfar under the consideration of sea clutter character
( 3 ) cfar方法：针对地杂波的特点，采用了单元平均恒虚警率( ca ? cfar )的方法。针对海杂波的特点，采用了双参数cfar算法。 - 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。
