摘　　要：混沌序列具有伪随机性,可作为噪声源。但是混沌序列在某些调制方式下,显现出其内部结构性,使得相关特性变的很差,难以应用。文中提出的具有MSPL混沌序列克服了这个问题,其相关特性和真正噪声的相同,并且兼具混沌序列易于使用的特点,适合作为噪声源运用于噪声雷达。因此,混沌序列也能运用于噪声雷达。The chaos series have pseudo-random characteristics,and can be utilized as noise source for noise radar.But for some kinds of radar modulation,the correlation performance of chaos series radar signals become poor because of chaos series inner structure.We propose to use a chaos series,MSPL series,and it overcomes the problem.Its correlation performance is as good as that of real noise series.Further more,being chaos series,it is easy to be utilized.Therefore,chaos series are suitable to be applied to noise ...
