导引头杂波信号数据库系统的设计与实现

导引头在应用过程中受到环境杂波的严重干扰,这些杂波主要有海杂波、地杂波、气象杂波和箔条干扰及有源电子干扰等,有时干扰甚至比有用回波更强,从而影响导引头探测目标的准确性。因此,对导引头环境杂波进行统计、检测、分析、特征提取及建模,进而建立导引头杂波数据库,将有助于导引头设计人员提高导引头测量的分辨率和精度。

The design and implement of signal database of the guidance head clutter

In practical application, the guidance head will be subject to the interference of the environment clutter,which is mainly sea clutter,land clutter,chaff interference as well as active interference and so on. Sometimes the interference is stronger than desired echo. So these factors affect the accuracy of the guidance head detecting the target. Thence, the statistics,dectetion,analysis,characteristic extraction and modeling of the guidance head enviroment clutter is necessary,which is convenient to the fact that the desinger of the gui-(dance) head enhance the resolution and accuracy of the guidance head measurement.
