Abstract
Common parameters for signal description can hardly meet practical requirement of radar signal sorting and recognition. Aiming at the problem of signal sorting system, DCT (discrete cosine transform) features and BT (product of bandwidth and time width) feature are introduced to form a new description vector. DCT features not only can reflect modulation mode but also are not sensitive to noise. BT feature can reflect some parameters of modulation. Both of DCT features and BT feature are easy to get. At last, results of weighted dynamic cluster show that DCT features and BT feature are effective for sorting.
