One Mathematical Model for Analyzing DBF Error in Smart Antenna System
Nowadays, digital beam forming (DBF) technology is more and more widely used in communication and radar systems. But in most situations, lots of errors such as the array position uncertainty or RF channel dissimilarity, A/D sampling deviation, etc., usually make the actual result deviated from the theory analysis. In this paper, firstly, the effects caused by these uncertainties are illustrated, then a new mathematical model is set up to estimate these errors, and finally the model is proved very useful by the simulation results.
