| 摘 要： | 为了提高步进频体制雷达的目标数据输出率,提出了一种基于搜索的步进频雷达信号速度补偿算法.该算法利用步进频方式下目标运动产生的二次相位项带来的影响,不用参差就能解速度模糊,从而完成速度补偿.研究了新算法对雷达参数设计的要求,理论和仿真结果表明了该方法的有效性,为步进频体制雷达的参数设计提供了理论依据.

| Abstract: | To improve the data rate of step frequency radar system,a velocity compensation method is proposed.It uses the effects of the quadratic phase created by moving target to obtain the real velocity without PRF stagger.Requirements of new algorithm for different parameters are studied.Theory and simulation results showed the efficiency of the proposed method.It provides a foundation for the theory of step frequency radar system. |

| Keywords: | step frequency velocity compensation moving target velocity ambiguity |
