| 摘 要： | 提出了一种提高时间分辨率取样积分器稳定性的平衡取样法。利用平衡混频器能够消除本振噪声的原理，将两个单二极管取样门接成对称结构，由一个取样门脉冲控制，通过差分放大消除取样脉冲、偏置电压和二极管参数等变化引起的基线漂移，提高了取样积分器的稳定性。同时，在基于取样积分器的近距离冲激雷达中，可以大大提高接收机的灵敏度和目标检测概率。

| Abstract: | This paper presents the balanced sampling-a way to promote the stability of high time resolution sampling integrator. The balanced mixer has the property of eliminating the local oscillation , so based on this princple ,two single diode sampling Clrcuits controlled by one sampling impulse are linked symmetrically. Through differencing amplifier , the datum line drift caused by the change of impulse , biase as well as diode is eliminated. and thus the stability of sampling integrator is promoted. Besides , in short-distance impulse radar based on sampling integrator ,the method can greatly increase the sensitiviy and target-inspecting rate of receiver. |
