The first step is the coarse range alignment [1], which places the scatterers in their respective range cells. After range compression using the Fourier transform of the original radar data with respect to frequency, the resulting data in the range domain is called a range profile. Each range profile at a different dwell time is correlated with a reference range profile. Relative range shifts for all range profiles are then derived by examining the location of the maximum value of the correlation output. The range shift is then smoothed using a polynomial procedure to better approximate the actual translation motion. Suppose the final detected range shift is R0(t), the coarse range alignment is done by multiplying the conjugate of the phase

第一步是粗1定范围,把各自不同散射体细胞. 傅立叶使用范围将压缩后的原始数据的雷达频率方面,由于数据的一系列广泛领域叫做姿态. 在每一个不同的形象不同的时间多参考各种姿态配合. 相对变动范围则是从所有各种情况的检查地点的相互产量最高值. 然后,经过了许多变化,以更好地利用多项式近似实际翻译程序动议. 如果最后发现各种变化R0(T),是由多粗的各种组合的配对词如下阶段
