摘　　要：提出一种应用于脉冲超宽带相关接收机的新型门控积分方法,它利用简单的线性时不变系统实现带清除的积分.这种门控积分方法简化了系统结构,易于实现.论文引入误差函数和干扰函数评价等效积分性能,还以二阶低通滤波器为例,给出了等效积分应用在模拟匹配相关时的性能计算结果,表明等效方法完全适用于脉冲超宽带模拟相关接收机.In this paper a novel gated integrating method for IR-UWB correlation receiver is proposed,which uses linear time-invariant system to approximate integrator with discharging.The novel integrating method simplifies the architecture of the receiver and can be easily implemented.We introduce an error function and an interfering function to evaluate the performance of the equivalent gated integrator.An example based on second-order low pass filer is given,demonstrating that the method we present is fully applicable to analog coherent receiver in IR-UWB.
