phase coded methods for resolving range ambiguity in pulse doppler weather radar are studied. a new kind of phase coded sequence and its spectral processing method are proposed.
该文研究了脉沖多普勒气象雷达中用于解距离模糊的相位编码法,给出了一种新的相位编码序列和相应的频域处理方法。
airborne pulse doppler weather radar could display clear colorized weather image dynamically on its screen and give pilots alarm about the extreme weather area to avoid risk betimes.
机载脉沖多普勒气象雷达则能够用清晰的图像实时显示出飞机前方的气象状况,并及时将极端天气的报警信息提供给飞行员,以提前躲避危险。
it is practical to measure phase noise from transmitter by means of a fine frequency spectrum analyzer. a measurement result of a s-band pulse doppler weather radar is also given in the paper.
具体提出了直接用分辨率比较高的高性能频谱分析仪测量发射机的相位噪声是可行的,最后给出了某型s波段脉沖多普勒天气雷达发射机相位噪声的测试结果。
c-band pulse doppler weather radar receiver is described in detail in this paper.
介绍了一种c波段脉沖多普勒天气雷达接收机。
