摘要

提出了反演目标冲激响应的修正最速下降法和估计逆卷积误差与控制迭代次数的相关系数判据．由导体球的瞬态电磁脉冲响应实测数据反演的结果表明：相关系数判据是估计逆卷积误差和控制迭代次数的一个简单可靠的判据；修正最速下降法是在时域反演目标冲激响应的一种有效方法，其反演效果优于修正共轭梯度法。

Abstract

Modified steepest descent method for inverting the impulse response of target and correlation coefficient criterion for estimating the deconvolution error and controlling iteration number of times are presented. The inversion results from the measured transient electromagnetic pulse response of a conducting sphere show that correlation coefficient criterion is a simple and reliable criterion and that modified steepest descent method is an efficient method for inverting the impulse response of target in time-domain and is superior to modified conjugate gradient method.
