Design Method of Reactance Loading Based Single Channel Five-Element Multi-beam Scanning Antenna Array
摘要
Abstract
To achieve multi-channel consistent receiving for multi-beam scanning antenna array, as well as to simplify its complex beam forming network, reactance-loaded five-element multi-beam scanning antenna array was designed, more importantly, in which only one output channel was required. Simulation results show that DOA estimation of up to four signals can be precisely performed by adopting MUSIC. Moreover, the impacts of signal-noise ratio, sample rate and angle space between signals on performance of DOA estimation were analyzed quantitatively. The design and simulation results of this antenna array are of certain significance to the optimization design and application of the reactance loaded HFSWR antenna arrays.关键词
