基于插值恢复多通道信号的单通道测向方法

Single receiver direction finding based on recovering multiple signals by interpolation

为克服多通道系统硬件量大、造价高及多通道间存在不一致性时性能恶化等不足,提出一种基于插值恢复多通道信号的单通道接收阵列测向方法。此方法采用一个接收通道,各阵元以时分方式工作,采用插值的方法恢复出各路信号,然后运用阵列信号处理算法进行测向。给出了应用该方法的具体步骤,通过仿真实验说明该方法的有效性。

An approach to direction finding based on single receiving channel is presented to overcome the shortcomings of multiple channel system, such as too complex and highly cost hardware, performance change for the worse due to the inconsistency among multiple channels. This approach needs one receiver with every antenna working in time-division mode, which uses the standard array signal processing algorithm to finding direction after recovering the multiple signals by interpolation. The steps for using this approach are described in detail and simulation results prove the effectiveness of this approach.
