Abstract: In this paper,tile peak sidelobe degradation due to the phase quantization in scanning phased array antenna is described.Several computation formulas used to estimate the peak sidelobe level degradation are given.It is shown that the theoretical analysis are in good agreement with the simulated computation results.
