摘要
提出了一种提高警戒雷达目标检测能力的数据处理方法———溯相关检测法。该法基于雷达帧间数据积累方式 ,利用目标的航迹相关特性降低噪声虚警 ,提高警戒雷达的信号检测能力和探测距离 ,模拟结果表明在满足虚警率为 10-E6的要求下 ,当输入信噪比为 3db时 ,其发现概率可由原来的 0 .5提高到 0 .9。
This paper gives a data-processing method to improve the detection ability of warming radar-A retrospective correlation method.The retrospective correlation method processes the features of echo track improving the detection ability of waring radar.The simulation results tell us that the detect probability of warning radar has been improves to 0.9 when the input signal's SNR=3db,probability of detection =0.5, probability of false-alarm =10-E6.
