Control of the beam direction is the main function of beam steering system of phased array radar. A kind of beam steering system based on PC104 computers is described in this paper.It is characterized by simplicity in hardware and flexibility in control and calculation. The principle and properties of the beam steering system are introduced in this paper.Besides,this paper introduces a new test method for phased array phase-shifting units with good accuracy .The method provides a reliable basis for the test and system maintenance.This method is suitable for small size phased array antenna.If we use modularized construction, it's also suitable for large phased array antenna.
