雷达组网能有效提高目标的检测性能。在目标瑞利起伏的模型下，噪声服从零均值高斯分布时，对比了秩K规则和最大信噪比规则这两种融合方法，对目标检测性能的影响。选取六部雷达进行数据融合，推导分析了在不同的虚警概率条件下，采用两种融合规则对雷达检测概率的提高程度，并指出在检测概率方面最大信噪比规则融合方法明显优于秩K规则融合方法，但雷达之间传输的数据量增大。

Radar netting can enhance the detection ability of targets. Detection property of netted radar using order-K and SNR maximization is analyzed under Rayleigh fluctuations and zero mean Gaussian distribution noise. The detection probabilities of the two rules are given under different false alarm probability when six radars are deployed. After compared with order-K quantifica- tionally, the excellent performance of SNR maximization method is proved while the bulk data transmission is needed.
