The radar signal real-time acquisition of raster scanning radar display system requires high efficiency and high-speed coordinate transformation. Based on the practical experience and the results of theoretical studies, an efficient and high-speed coordinate transformation algorithm EPROM-based carry-save algorithm and its hardware realization are presented for the raster scanning radar display system. According to this algorithm, an efficient method to overcome display blind area and dead address is given. The quality of the image display has been greatly improved.
