阵列信号单信道处理技术

阵列信号处理已广泛应用于许多电子系统中，如微波无源比幅测向系统等，但通道间的振幅和相位的不平衡常常引起较大的测向误差。为了匹配通道间的振幅和相位平衡，可利用卫星通信中的多址联接技术（如ＦＤＭＡ、ＴＤＭＡ或ＣＤＭＡ）构成单信道处理系统来代替多信道系统。文中详细地研究了ＣＤＭＡ单信道系统，建立了系统模型，分析了系统特性，模拟结果证明了这种单信道理论和技术的可行性。

Antenna Array Monochannel Processing Techniques

Array signal processing has been widely applied in many electronic systems, such as themicrowave passive direction finding (DF) with amplitude comparision. But the unbalance of amplitude or/and phase among the channels always introduces a large DF error. In order to matCh the amplitude or phase balance among multiple channels in the array passive DF system,a few multiple acccssing techniques, suchas FDMA (Frequency Division Multiple Accessing), TDMA (Time Division Multiple Accessing )and CDMA (Code Division Multiple Accessing),Which have been developed in satellite communication,can be utilizedto build a monochannel processing system replacing the multicahnnel system. The CDMA monochannelprocessing technique is studied in detail in this paper. First,the model of CDMA monochannel processing isconstructed, then, a few of its important properties are analysed. Finally,the simulation results demonstratethat the theory and techique proposed in this paper are valid.
