对频域非完整信号的单基线干涉仪测向
Direction Finding of Signals with Partial Frequency Elements Using Single Base-line Interferometer
摘要
Abstract
With the development of signal diversity and the wide application of ultra-wide band signals,the bandwidth of signal becomes wider and wider.Currently,many reconnaissance receivers with narrow receiving band can not acquire all the frequency ele-ments of this kind of signals simultaneously.However,the direction finding of these signals is quite necessary for spectrum surveillance and electronic reconnaissance.In this paper,the distortion of received signal is discussed on condition that the frequency bandwidth of the receiver is narrower than that of the signal.The mathematic model for signal with partial frequency elements is constructed,based on which the direction finding is accomplished using the single base-line interferometer direction finding theory without ambiguity,and the integrative processing method for partial phase information in frequency domain is analyzed.The simulation results show that the direc-tion information can be acquired for ultra-wide band signals of communication and radar, which validates the feasibility and practicability of this method.关键词
