通过分析多传感器检测系统在固定融合规则下最优中心融合问题，研究了在模型为确定信号相关高斯噪声影响下的次最优局部传感器数据压缩问题，提出了一种优化局部迭代决策方法。该方法通过指定一条快速搜索路线，将原有的二维搜索问题转化为单变量的峰值搜索问题，简化了搜索算法，提高了搜索效率，同时保证了迭代精度。仿真结果说明，该方法搜索速度快。

The fast Local Compression Rule In Distributed Signal Detection System

After analyzing the result of optimal central fusion under given fusion rule, A novel optimal local compression rule is presented. The optimal local sensors' data compression is also studied. With a given optimal search path, the question of search the optimal result in two dimension is transform into finding the maximize result with one variable. This algorithm makes the things simple, improves the search efficiency and optimizes the result. The simulated result shows that this algorithm have better accuracy, fewer CPU time.
