| 摘 要： | 介绍了频率步进雷达中多普勒效应对距离像的影响,根据频率步进雷达中常见运动补偿方法的优缺点,提出了一种仅利用单帧数据即可实现速度估计和补偿的方法,为了提高该方法的抗噪声性能,采取对算法进行迭代运算得出有效速度估计值的策略.理论分析和计算机仿真结果表明,该方法只需几次迭代(一般为3次或4次)即可得出有效速度估计值;该算法具有可行性.并兼有测速精度较高、运算量较小、抗噪声性能较强的优点.

| Abstract: | The influence of Doppler effect on range profile in stepped frequency radar is introduced. According to the advantages and disadvantages of the commonly used velocity compensation methods in stepped frequency radar,a velocity compensation method based on one frame data was put forward.In order to improve the anti-noise performance,iterative execution of the algorithm was performed to obtain the optimal velocity estimate.The theoretic analysis and simulation results indicated that:1) The method can get the o... |
