Joint detection and direction finding using a switched antenna array

Abstract

Algorithms for signals joint detection and direction at frequency area in a wide frequency band with no overlap of spectra of adjacent channels obtained through switched circular antenna array are developed and researched. The energy and the computational advantage of the algorithm with the primary detection on amplitude spectrum and the secondary direction finding at samples containing signal components, before the algorithm with the primary direction finding in all frequency samples with subsequent detection of the frequency samples that contain signal components is showed.
