Abstract

Digital phase shifter is widely used to achieve space scanning in phased array antenna. The quantization error will produce for discontinuous phase shifting of digital phase shifter. This paper introduces an approximate formula, derived by adding sub-array virtual elements and using the principle of pattern multiplication, about beam pointing accuracy of uniform linear array in condition of phase quantification. And a compensation method for sub-array elements is put forward to make approximate formula after compensating better estimate the precise pointing error. Simulation results show the effectiveness and correctness of the compensation method.
