根据雷达理论可知,提高虚警概率可以提高检测概率,对于弱小目标及远距离目标的检测十分有效,然而受到数据处理能力的限制,通过提高虚警概率实现提前发现目标的方法没有得到充分利用。本文提出的数据预处理新方法可以有效的剔除杂波点,对提高雷达的作用距离及弱小目标的检测十分有利。

According to radar theory,radar detection probability can be improved by increasing false alarm rate,which is more effective when a radar is detecting targets with small-size or at long distance.However,due to limitation of data processing capability,the methods to find a target in advance by increasing false alarm rate has not been applied fully.The new data pre-processing method proposed in this paper can effectively eliminate clutter points,which is effective to improve operating range of radar and detect probability against small/weak targets.
