卡尔曼滤波法
某火箭在空中沿直线做匀加速飞行，加速度为 ，发动机推力的波动一定会引起加速度波动，雷达以间隔时间不断测量该火箭距离远点的距离 ，由于雷达的测量噪声使得火箭距离测量值 中含有噪声。现在欲通过雷达对火箭距离的测量数据求得火箭的真实距离、速度和加速度。(A linear constant acceleration rocket flight in the air along the acceleration, the engine thrust fluctuation will cause the fluctuation of acceleration time interval measurement, radar to constantly the rocket from the far point of the distance, because the noise radar makes the rocket range measurements with noise. Now, the real distance, velocity and acceleration of the rocket are obtained by measuring the distance of the rocket by radar.)

波数域算法又称为距离徙动算法（Range Migration Algorithm，RMA）或-算法，由Cafforio等提出。该算法分析距离处理后信号的二维频谱，通过二维频域匹配滤波进行相位补偿，在完成方位聚焦的同时完全校正距离徙动。由于其中的Stolt变换能克服SAR信号中距离徙动和SRC对斜距的依赖，因此波数域算法是一种理想的成像算法，尤其在处理大斜视角和长合成孔径的SAR数据时。但Stolt变换需要插值，降低了处理效率并引入额外的误差。(The wavenumber domain Algorithm is also called Range Migration Algorithm (RMA) or -algorithm, which is proposed by Cafforio et al.The algorithm analyzes the 2-d spectrum of the signal after the distance processing, carries out phase compensation through the 2-d frequency domain matching filter, and completely corrects the distance migration while completing the azimuth focusing.Because the Stolt transform can overcome the SAR signal range cell migration and SRC dependence on oblique distance, thus wavenumber domain algorithm is an ideal imaging algorithm, especially when dealing with large squint Angle and long synthetic aperture of SAR data.But Stolt transformation requires interpolation, reduces processing efficiency and introduces additional errors.)
