Abstract


Nowadays,the VLSI circuit technology and computer technology have gained a tremandous development. It gives the potential to the real-time realization of the Large array adaptive beam forming algorithm.On the one hand,The engineering application of the adaptive beam forming technology enhanced the radar system active disturbance rejection and survival capability effectively,on the other hand, simultaneous multi-beamforming makes the radar system truly have the ability of searching, verification and tracking multi-targets in real-time.Papers some model receiver array radar development for background, carried out studies in research techniques of the digital beam forming, its major content includes:(1) A software scheme for digital beam forming processor of receiver array is proposed.(2) According to project timing request and interface request,the design based upon data stream driving mode has finished with the implementation of the digital multi beam forming. the whole program includes:the data stream sending and receiving control moudle,the initialization control moudle,the beam forming moudle.(3)The simulation results of the antenna patterns indicates that,the proposed digital beam forming processor in this paper works correctly and reliably, it is able to form180,15and3beams to cover appointed airspaces in searching, verification and tracking modes or form beam head expectation objective.And the digital beam forming processor has the ability of adaptive jamming cancellation in verification and tracking modes.
