基于惯性约束聚变的激光靶耦合过程会产生大量的电磁脉冲,严重影响诊断设备的正常运行和测试数据的精确采集。该文采用Tikhonov正则化结合L-curve参数优化法,通过把电场、电压和传递函数的关系离散化,绘制L曲线图以确定最适正则化参数,从而对测试数据进行优化。结果表明,L-curve在成功消除病态数的同时还具有较强的抗噪声抗干扰性能,达到明显数据优化作用。
The laser target coupling process based on inertial confinement fusion will produce a large number of electromagnetic pulses, which seriously affect the normal operation of diagnostic equipment and the accurate collection of test data. In this paper, we use Tikhonov regularization and L-curve parameter optimization method to optimize the test data by discretizing the relationship between electric field, voltage and transfer function, and drawing the L-curve to determine the optimal regularization parameter. The results show that the L-curve has strong anti-noise anti-jamming performance while successfully eliminating pathological numbers and achieves obvious data optimization.
