| 摘 要： | 本文应用模拟退火算法来改进超声回波模拟问题。仿真结果表明，该算法不需计算梯度，与初始选择值无关，并可在较大范围内搜索。从而避免了应用高斯-牛顿迭代法模拟超声回波的缺陷，即解决了选择的初始值只有在真实值附近才能迭代出最优解的问题。

| Abstract: | The simulated annealing method is applied to the simulation of ultrasonic echo in this paper, The algorithm needs not calculate gradient, is unconcerned about the initial wlue, and searches in a greater scope. So the disadvantage of the Gauss-Newton Method such that the result can only be calculated when the initial value close to the true value is avoided on ultrasonic echo simulation. |
