摘　　要：采用低频偏置和频率搬移是获取动目标的常规方法,它对微波设备性能的要求主要体现在频率稳定性上,关于此方面研究已经非常充分和完善,其作为外场应用时受到多方面因素限制。本文给出了一种在微波频段直接获得雷达所需的外场动目标的实现方法,对微波设备性能的要求降低,适应了雷达检验和标校需求,并经过实际应用验证获得了满意的效果。In the way of biasing in low frequency and frequency conversing to capture a moving - target is in general, the frequency stability of the microwave equipment will be requested mostly, the investigation about this aspect has been very plenty and perfect already, it would be limited of use in outfield by factors in many aspect. A realizable method was giving in this article that to capture a outfield moving-target needed of RADAR, directly in the microwave band, greatly, debasing on the microwave equipment, promising the requirement of checkout and calibration of RADAR, also, validated by practice applied and acquired contentment effect.
