摘要
基于多径环境下阵列米波雷达测高的实现问题,本文将神经网络中的BP网络和RBF网络应用于米波雷达测高,分析和比较了这两种方法的性能,研究了通道幅相不一致和反射系数失配对两种方法测高精度的影响.理论分析和仿真结果验证了基于这两种神经网络的米波雷达测高方法的有效性和稳健性.
In this paper, BP network and RBF network are applied to meter-wave radar height-finding. The per- formances of both methods are analyzed and compared with each other, the height-finding accuracies of both me- thods are evaluated under the low signal-to-noise ratio, channel errors and mismatch reflection coefficient situations. Theoretical analysis and simulation results show the effectiveness and robustness of meter-wave radar height-finding using BP and RBF networks.
