Abstract
In order to overcome the limitations of phased array radar technology,
the researchers proposed frequency diverse array technology to achieve
accurate detection and tracking of target direction. In this paper, a
method of distance and angle estimation based on DFT transform is
proposed for frequency transform array. By cross-correlating the
received data, a new received signal vector is established and solved by
constructing an equation. Compared with other methods, this method
overcomes the problem that FDA radar is prone to fuzzy estimation and
insufficient resolution in target parameter estimation. It can not only
directly estimate the distance and angle of the target, but also
effectively improve the target resolution.
