| 摘 要： | 由于高分辨雷达的分辨率远小于目标尺寸，使得目标呈多散射中心，回波能量沿时间分布，从而降低了峰值幅度，增加了目标检测难度。因此文中基于一维距离像提出了一种新的高分辨雷达检测方法，该检测方法将一维距离像看作随机脉冲串，利用一维像强散射点的位置信息和幅度信息联合进行检测，自适应地估计目标一维距离像长度，提高了高分辨雷达检测性能。

| Abstract: | Due to the size of the target is larger than the range resolution cell of high resolution radar, the backscattered power of the target is recorded as a function of time. In this paper, a novel method based on random parameters pulse train is proposed for high resolution radar target detection. Simulations show that the performance of high resolution radar detection can be improved effectively by using the new method. |
