| 摘 要： | 针对高速弹载平台加速度大相参积累效果变差需进行加速度补偿的问题，研究了信号波长和积累时间与加速度之间的关系，推导了利用多普勒谱宽计算加速度的公式，提出短时间积累使用弹载惯导设备输出加速度值进行补偿、长时间积累使用惯导数据与多普勒谱宽测量加速度相结合的加速度补偿方法。仿真验证了该方法的有效性。

| Abstract: | The problem of high‐speed missile platform with high acceleration leads to poor coherent accu‐mulation effect ,requiring acceleration compensation .Aiming at this problem ,the relationship between signal wavelength ,accumulation time and acceleration is researched . The acceleration formula from the Doppler frequency width is derived .An acceleration compensation method is proposed for a short time accumulation , by using missile inertial navigation equipment to output acceleration value .And an acceleration compensation method is proposed for a long time accumulation ,by combining the inertial navigation data and Doppler width acceleration measurement .The simulation results verify these methods . |
