摘　　要：将单脉冲雷达技术与超宽带雷达相结合,提出了一种新的幅值比较超宽带单脉冲雷达接收机结构,该接收机通过4个加脊喇叭方形馈源阵列天线接收回波信号,经比较器电路后产生和、差信号,对信号进行互相关处理及幅值比较处理后即可确定目标的位置。最后给出了超宽带单脉冲接收机的仿真过程与仿真结果,证实了所得的和、差信号与测量值之间具有较好的一致性。A novel amplitude-comparison monopulse receiver architecture is proposed for ultrawideband radars.This receiver received the incident pulses by square-feed array of four ridged-horn antennas,comparator circuit generates the monopulse sum and difference signals,cross-correlation receivers detect the monopulse signals,and an amplitude-comparison monopulse processor determines the target s angular position.Finally,the derived sum and difference patterns are compared with measured patterns,and they show good ag...
