- 摘要:
- 由于斜视随机噪声合成孔径雷达（SAR）的信号没有解析式，且通常的线性调频信号SAR的成像算法不再适用，提出了一种随机噪声斜视SAR距离多普勒（RD）成像算法。该算法根据随机噪声信号距离向处理的特点，先进行距离向部分处理，然后在二维频域进行距离弯曲和距离走动校正，因此，其对小斜视随机噪声SAR能获取较好的图像。仿真结果表明该算法的有效性和正确性。
- Abstract:
- For the signal of random noise SAR has no mathematical expression,and normal algorithms of LFM SAR can not be applied to random noise SAR,the paper proposed a Range-doppler imaging algorithm for random noise SAR with a squint angle.Considering the characteristics of range processing of random noise SAR,the derivation of the algorithm with fractional range processing and range correction in frequency domain was given after dealing with the range dimension.The proposed algorithm provided good random noise SAR image with a squint angle.The simulation result illustrated that the algorithm was feasible and correct.
