摘要
在现代短波通信中,作为低截获率通信手段之一,单个信道内信号持续时间大大缩短,从而增加了信号检测与提取的难度。提出一种基于阵列的信号检测与提取算法,通过利用阵列信号的特性,获得了较好的信号检测与提取效果。并将其与单通道时的信号检测与提取算法进行比较,证实了算法的优越性与可靠性。
In modern shortwave communication, the length of very short for reducing the probability of being intercepted, thus traction increased. We signal existence time in single channel is the difficulty of signal detection and exsignal detection and extraction, and obpared with the single - channel signal detection/extraction algorithm, the proposed performance and higher robustness.
