摘　　要：分析了取样平均器在无载波超宽带运动目标检测雷达中的应用原理 ,对一种取样平均器的工作过程作了推导 ,建立了取样平均器的数学模型 ,并进行了仿真。结果表明The principle of applying sampling averager to carrier free ultra wideband radars for moving target detection is analyzed. The working process of a sampling averager is deduced, and its mathematical model is proposed. Based on this model, a simulation is carried out, with the result that the time domain noise elimination method based on sampling and averaging can eliminate noise or high frequency jamming effectively.
