摘 要: 基于双向抛物线方程模型,应用逆抛物线方程法对二维空间目标进行定位。针对传统逆抛物线方程法难以分离目标回波和背景杂波的问题,采用时间反演自适应消除法对背景杂波进行滤除,结合逆抛物线方程法完成空间场分布的反演,并通过寻找最大场强坐标的方式近似估计目标位置,有效地解决了强杂波环境中误定位的问题。最后,对平静海面上的探测过程进行模拟仿真,计算结果表明:该方法能够取得较好的纵向定位精度。
关 键 词: 电磁学;抛物线方程法;时间反演算法;逆抛物线方程法;杂波消除;目标定位

Abstract: Based on the two way parabolic equation model, the inverse parabolic equation method was applied to the two-dimensional target localization problem. However, while the traditional inverse parabolic equation method was difficult to separate the target echo and the background clutter, time reversal adaptive interference cancellation method is used to eliminate the background echo, and then inverse parabolic equation method is applied to determine the spatial field distribution of the whole region. The target location is estimated by the maximum electric field strength position. The combined algorithm eliminate the localization error problem effectively for strong clutter environment. Finally, the longitudinal localization accuracy is verified by the numerical example.
