为了更好地减小雷达的虚警，探讨了大目标在旁瓣产生虚警的原因，分析了旁瓣大目标在90。扫描内的目标位置。通过在距离向搜索满足位于相同距离单元或位于呈线性关系的距离单元的连续多频点目标，提出了判定大目标的方法以及利用2次FFT最大值判定大目标真实方向的方法。将2次FFT仿真数据代入算法进行仿真，结果表明：该方法能很好地消除旁瓣大目标带来的虚警。

For reducing radar＇s false alarm, the paper analyzes the reason of false alarm for big RCStarget in the sidelobe. The location of big RCS target is caught. Through searching in the same distance cell or the linear distance cell in the radial distance at many frequency points, the method ofmaking sure big RCS target is put forward and the way of making sure the big RCS target＇ s azimuth using the maximum of twice FFT results is constructed. The results of twice FFT emulational data indicare that the method can remove false alarm of big RCS target in the sidelobe.
