本文首先在考虑了目标电磁散射全响应的条件下,以其传递函数为基础,应用函数逼近的理论和方法,建立了求取目标特征系数的实用算法。然后,以特征系数作为识别特征量,采用最小距离分类法,实现了自动目标识别。 In this paper, based on the transfer function and the theory and method of function approximation, a practical algorithm for obtaining the target characteristic coefficient is established under the condition of considering the full response of target electromagnetic scattering. Then, taking the characteristic coefficient as the identification feature quantity, the minimum distance classification method is adopted to realize the automatic target recognition.
