收发分置雷达容错栅栏覆盖的优化部署

Optimal placement for fault tolerant barrier coverage in bistatic radar sensor networks

针对收发分置雷达栅栏覆盖的部署位置容错问题,研究了雷达节点在有部署位置误差情况下的最大间隔部署策略。分析发现当雷达节点有位置误差时的最大间隔部署是一个非线性规划问题,通过限制相关条件得到了最大间隔部署问题的次优解;设计了贪心搜索算法实现了两个发送器之间的任意个数接收器的最优部署,最终找到了收发分置雷达的最优部署序列实现容错栅栏覆盖的最优部署,使得栅栏的探测性能最优。

This paper focus on the position fault tolerant of barrier coverage in bistatic radar sensor networks, studied the maximum interval deployment strategy when there is position fault of sensor node. It is found that when the radar node has position fault, the maximum interval deployment is a nonlinear programming problem, and the second-best solution can be got through restricting some conditions. The greedy-search algorithm is proposed to get the optimal deployment strategy of any number of receivers in between two transmitters, and finally found the optimal placement strategy for fault tolerant barrier coverage in bistatic radar sensor networks, and bring the barrier the optimal detection performance.
