宽带相控阵雷达的波控系统设计

宽带相控阵雷达要求波控系统不仅能完成窄带方式下的移相控制,还应具有宽带方式下的延时控制,实现雷达系统高分辨探测.文中采用了"广播式传输、分布式运算"的波控系统方案,设计了基于数字信号处理器(DSP)的波束控制器,完成波束的实时运算和相位控制,在子阵级和单元级实现了宽带方式下延时控制算法,并在工程上得到了验证.

Design of Beam-Steering System for Wideband Phased Array Radar

In the wideband phased array radar, beam-steering is required not only to shift phase in narrow band, but also to control delay in wide band which realizes high resolution detection for radar system. A design of beam-steering system which adopts "broadcast type transmission and distributed calculation" is presented in this paper. Based on digtal signal processing (DSP) com-ponents, the system achieves real time beam control and phase shift control. Delay beam steering control arithmetic is achieved at sub-array and module level when wideband phased array radar works in wide band. The design has been validated.
