Super-resolution direction finding algorithm for arbitrary number of channels

提出了一种可适用于任意通道数的超分辨测向算法.通过多路开关切换实现对协方差矩阵的测量,进而重新构造了天线阵列导向矢量,实现超分辨测向.当前的算法只能用于通道数等于1或天线阵元数的情况,新算法突破了该限制,拓展了超分辨测向算法的适用范围.对算法进行了详细的理论推导.计算机仿真结果表明该算法性能优于单通道算法,接近经典测向算法.

A super-resolution direction finding algorithm for arbitrary channel num- ber condition is proposed. Switching to measure the covariance matrix by multiplex switch, and then reconstructs the array steering vector, to achieve super-resolution direction finding. The current algorithm can only be used for the channel number which is equal to 1 or the number of antenna array elements. The new algorithm o- vercomes the limitation, expanding the scope of application of the super resolution direction finding algorithm. The algorithm is deduced in detail. The results of com-puter simulation show that this algorithm is better than the single channel algo-rithm, close to the classical algorithm for direction finding.
