| 摘 要： | 根据雷达发射恒定载频信号时匀加速目标的回波为线性调频（LFM）信号的特点，研究了在单脉冲内基于Hough—Ambiguity变换（HAT）估计目标径向加速度的问题。首先，采用Hough—Ambiguity变换得到信号的调频斜率；进而，根据调频斜率估计出目标径向加速度；最后，仿真实验结果验证了方法的有效性。

| Abstract: | Radar echo is linear frequency modulated signal when radar transmit constant carrier frequency signal. In this paper, the problem of radial acceleration estimation in one pulse was dealt with based on Hough-Ambiguity transformation, and then acceleration was estimated. Firstly, the frequency modulation slope was gained by Hough-Ambiguity transformation. Then, the radial acceleration was estimated by using the obtained frequency modulation slope. Finally, computer simulations verified the effectiveness of the proposed algorithm. |
