- Abstract
Using multiple beams simultaneously for highly precise continuous angle tracking of multiple targets is a new and important research area for phased array. In view of this,a method is proposed that uses recursive accumulation to control phase and create an integral part,based on which a basic first-order angle tracking loop is constructed. In the loop,the number of integral parts can be increased to constitute a highorder automatic adjustment system to achieve high precise continuous angle tracking. The block diagram of the system is given,and the commonly used expression of the closed-loop transfer function of the second order loop is deduced. The results show that the closed-loop transfer function of the second order loop is similar to that of the phase-locked loop,and many related achievements of the phase-locked loop technology can be applied. In addition,the angle tracking methods such as projection plane rotation method and spacedomain window sliding method are also introduced. Although their tracking schemes are different,they both have the same closed-loop transfer function model.
