| 摘 要： | 为了充分利用宽带线性调频(LFM)信号的时域信息,实现对此类信号的阵列快速高精度测向,结合线性调频信号调制样式的特殊性,提出了一种基于阵列接收数据时域延迟相乘的宽带线性调频信号阵列测向新方法.该方法利用窄带阵列测向方法实现了对宽带线性调频信号的快速测向,其计算效率和对阵元间距的适应范围均优于常规的宽带聚焦类测向方法.仿真结果表明新方法在处理线性调频信号时具有比常规的宽带CSM方法更优的性能.

| Abstract: | In order to fasten and improve the bearing estimation method for wideband Linear Frequency Modulated(LFM)sources by exploiting the temporal information of this kind of signals,a new direction finding method based on the product of the array output with its temporally delayed version is proposed.The new method succeeded to estimate the direction-of-arrival(DOA)of the incident wideband LFM signals via narrowband subspace-based method,and exceeded normal wideband direction finding methods in computational effi... |
