 系统接收信号处理电路设计是微功率冲击雷达技术实现的关键部分。设计了一种基于相关检测和距离窗的双门限检测的微功率冲激雷达接收系统电路,具体分析了接收信号处理电路的工作原理。通过仿真和试验,该接收系统电路可获得具有平坦的3 dB通频带幅频特性的带通、低通和高通滤波器和Q值大于5的50 Hz陷波器,达到理论设计要求,电路结构简单、成本低、性能好,在超宽带雷达技术中具有应用价值。

Abstract:
 The key of MIR (Micropower Impulse Radar) technology lies in how to design an effectual receiver circuit. Based on correlation detection and detection threshold, MIR receiver circuit is designed, with emphasis on the receiver signal processing circuit. It is simulated and verified with satisfying results to get a flat 3dB passband for the amplitude frequency characteristics of the band-pass, low and high-pass filter and Q value more than 5 for the 50 Hz trap filter.The design achieves the theory design requirements with simple structure, low cost and good performance. It has definite practical value in ultrawideband technique.
