摘　　要：针对带状栅栏覆盖中位置受限情况下的布站问题,本文提出了一种基于异构双基地雷达的优化布站方法.该方法以异构双基地雷达布站模式及布站序列的性质为基础建立问题的优化模型.为了求解该模型,本文将优化模型分解为三层.内层固定异构发射器的位置,以该位置为界将栅栏覆盖区域分为两段,联合采用整数线性规划和贪婪方法确定单条栅栏的最小布站成本及布站序列;中间层在栅栏宽度固定的情况下,对所有可能的异构发射器位置计算最小布站成本,并确定单条栅栏的最小布站成本;外层引入两种布站策略确定栅栏宽度:一种是非等分策略布站方法,另一种是等分策略优化方法,并相应给出两种算法分别确定最小布站成本,子栅栏的布站序列和数量.最后通过仿真实验验证了这两种算法的可行性与有效性,实验结果表明非等分策略与等分策略相比,布站成本可降低6%,使用的发射器数量可减少10%.For the deployment problem with constrained locations in belt barrier coverage,this paper proposes an optimal deployment method based on heterogeneous bistatic radars.The method proves the properties of deployment pattern and sequence for the heterogeneous bistatic radar.Then based on these properties,an optimization model of the problem is proposed.This paper divides the optimization model into three layers to solve this model.In the inner layer,the position of the heterogeneous transmitter is fixed,and the barrier coverage is separated into two segments by this position.An algorithm that integrates the integer linear programming and greedy methods is exploited to determine the minimum deployment cost and deployment sequence for a barrier;In the middle layer,with a given width of the barrier,the minimum deployment cost is calculated for all possible heterogeneous transmitter positions,then the minimum deployment cost of a barrier is determined;In the outer layer,two deployment strategies are introduced to determine the barrier widths,one is barrier width non-equalization strategy;the other is the barrier width equalization strategy,correspondingly,two algorithms are given to determine the minimum deployment cost for the entire area,the deployment sequences and their numbers of the sub-barriers.Finally,the feasibility and effectiveness of these two algorithms are verified by simulations.The simulation results reveal that the non-equalization strategy is superior to the equalization strategy,leading the deployment cost can be reduced by 6%and the number of transmitters can be reduced by 10%.
