| 1. | A new conclusion in ca - cfar detection 单元平均恒虚警率检测中的一个新结论 |
| 2. | Cfar target detection in sar imagery 合成孔径雷达图像的恒虚警率目标检测 |
| 3. | The high false alarm rate is the main problem which puzzles the research and application of the bit technology 虚警率较高始终是困扰bit技术研究和应用的主要问题之一。 |
| 4. | First , we propose a kind of constant false alarm rate ( cfar ) target detector to find potential targets from scenario 利用恒定虚警率( cfar )检测算子,从场景中发现潜在目标。 |
| 5. | Due to energy spread of return target signals between doppler cells , both false alarms and missed alarms increased 机动目标回波能量在多普勒单元间的扩展还会导致弱目标的漏检和虚警率的提高。 |
| 6. | The characters of this device were high sensitivity , wide - angle warning resign , accurate azimuth angle of the coming laser and low wrong - warning rate 此激光预警器的特点是灵敏度高、视场宽、测向精度高,且虚警率极低。 |
| 7. | 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。 |
| 8. | This method utilizes the distribution property of image intensity . given the false alarm probability , the threshold for likelihood difference can be determined 该方法利用sar图像的强度分布特性,根据虚警率确定相邻区域之间存在边界的似然差函数的阈值。 |
| 9. | ( 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。 |
