Abstract: Radar information visualization is one of the most important aspects of modern battlefield visualization, it is a crucial role for the control of the overall situation of the battlefield. Aimed at the problem of data loss after visualization of two-dimensional radar envelope data, in this paper, the radar envelope detection algorithm is proposed to extract the multi-radar envelope, and the algorithm can accurately retrieve the original data corresponding to each boundary line. In addition, for the slow problem of radar envelope drawing, this paper uses bitmap technology to quickly maping the envelope. The experimental results show that the method can quickly update the radar envelope.
