The speed of modern vehicles becomes higher and higher along with the development in supersonic technology and this brings challenge to detection by conventional radars. This article studies the problems encountered in high-speed target detection by conventional radars. Firstly, it analyzes the factors affecting the range migration of high-speed target echo envelope and gives three algorithm structures for high-speed target range migration. Secondly, this article reviews the characteristics of the three algorithm structures and, based on coordinate transformation, proposes a high-speed target detection algorithm using frequency compensation structure; this algorithm is capable of accomplishing first-order and second-order term compensation of high-speed target range migration. Finally, the validity and advantage of this algorithm are verified by experiment data.
