Abstract:

For the phased array radar is small,the beam control system in order to reduce the amount of hardware equipment,meet the requirements of fast beam transformation,the use of centralized control mode,the look-up table calculation method to realize beam control code operation and status code control.Design calculation of wave control arithmetic based search DSP code,FPGA code base according to the array according to the order of parallel computing in each unit of wave control code,effectively reducing the beam conversion time.Using DSP and FPGA combination of work style,fast operation speed,flexible programming,debugging convenient,also has certain reference for the design of distributed beam control.

Key words: phased array radar;beam control;look up table
