摘要
Gram-Schmidt正交投影算法在自适应波束形成中有广泛应用,但是对于连续波体制雷达,接收信号中存在期望信号,算法会将期望信号抑制掉,而且作为信号子空间算法,在接收信号相干时将失效。论文针对阵列接收信号中含期望信号,并且信号相干情况下,提出通过空间平滑处理,对接收信号消除期望信号并解相干,有效抑制干扰,并保证期望信号不被抑制。
Gram-Schmidt orthography projection algorithm is applied in adaptive digital beam forming,but for continuous wave radar,the target signal included in the received signals will be restrained,so in this situation and the traditional algorithm as the signal subspace algorithm will also be disabled if the received signals are coherent with each other.Under the situation that the array signals contain the desired signal,and the signals are coherent,through space smoothing process,the target signal is eliminated from the received signals,and the jamming signal decorrelation is received,so as to effectively suppress interference,and to ensure that the desired signal is not suppressed.
