摘要

为满足现代城市建设中地下金属目标探测的需要，针对入射场中单个激磁线圈空间发散、聚焦能力差的问题，基于空间磁场矢量叠加原理，构建了锥形聚焦线圈阵列拓扑结构，建立了线圈阵列聚焦磁场解析模型，分析了线圈阵列各结构参数对聚焦特性的影响。设计了基于模拟退火的改进粒子群优化算法（SA-IPSO）来求解线圈结构参数的最优解，形成了磁场强度分布更集中、聚焦性能更好的瞬态电磁（TEM）探测激励线圈阵列结构。实验表明，在阵列线圈结构参数最优解的情况下，60% 的高磁场能量集中在半径为 30 cm 的磁聚焦区域，最大磁场强度为 1.1times 10^{-{4}}$ T，与未优化结果相比，磁场强度提高了 10%，磁场聚焦范围缩小了 25%。聚焦线圈阵列结构优异的聚焦效果对 TEM 检测中的线圈优化设计具有一定的参考价值。

Optimal Design of Excitation Coil for Transient Electromagnetic Detection Based on Incident Field

To meet the needs of underground metal target detection in modern urban construction, in view of the problem that a single exciting coil in the incident field diverts in space and has poor focusing ability, based on the principle of spatial magnetic field vector superposition, the topology structure of conical focusing coil array is constructed, the analytical model of focusing magnetic field of the coil array is established, and the influence of each structural parameter of the coil array on focusing characteristics is analyzed. An improved particle swarm optimization algorithm based on simulated annealing (SA-IPSO) was designed to solve the optimal solution of coil structure parameters, and a transient electromagnetic (TEM) detection exciting coil array structure with more concentrated magnetic field intensity distribution and better-focusing performance was formed. Experiments have shown that under the optimal parameter solution of the array coil structure, 60% of the high magnetic field energy is concentrated in the magnetic focusing area with a radius of 30 cm, and the maximum magnetic field intensity is

$1.1\times 10^{-{4}}$

T. Compared with the unoptimized results, the magnetic field strength has increased by 10%, and the magnetic field focusing range has been reduced by 25%. The excellent focusing effect of the focusing coil array structure has a certain reference value for coil optimization design in TEM detection.
