面阵系统所采用阵元数多,数据量大,对信号处理机的实时处理能力要求非常高.系统采用基于参考信号的LMS算法,收敛速度较快、运算量低,且易于硬件实现.系统平台采用目前流行的DSP&FPGA架构,具有高速运算和处理能力,解决了面阵系统对实时处理机的苛刻要求.测试结果表明,系统能自适应地控制天线阵列方向图在用户信号方向产生高增益波束,在干扰信号方向产生较深零陷,并实现零误码率通信.%The element number and the data quantity of the planar array are quite large,so it requires high performance for signal processor. LMS algorithm based on reference signal has fast convergence and low computadion.also easy to be implemented. The popular DSP&FPGA architecture with high-speeding calculating and processing ability is used by the system platform, which solves the real-time demanding of the planar system. The test result shows that the system could adaptively steer the array directional pattern to form the main narrow beams with high gain in the direction of the users' signals while deeply nulling the interference signals, also achieve zero error rate communication.
