连续波随机噪声SAR距离-多普勒成像算法

连续波随机噪声合成孔径雷达具有十分优良的低截获特性、抗干扰特性和电磁兼容性,因而受到广泛的关注。针对连续波随机噪声合成孔径雷达的天线连续运动引起的问题，提出了两种距离-多普勒成像算法。通过分析连续波体制下随机噪声合成孔径雷达距离向信号的长度，推导了在频域和时域校正在距离向信号持续时间内天线连续运动引起的相位项的两种距离-多普勒成像算法。最后，通过点目标仿真实验，验证了算法的有效性。

Range-Doppler imaging algorithm of CW random noise SAR

Possessing fine low probability of intercept, electronic counter-countermeasure capability and electromagnetic compatibility, the continous wave random noise synthetic aperture radar (CWRN SAR) has been given considerable interest. Aiming at the problem caused by antenna continuous motion of CWRN SAR, two modified range-Doppler imaging algorithms are proposed. The signal length of SAR range direction is analyzed, and two modified range-Doppler imaging algorithms that correct phase in frequency and time domains during the duration time of signals in range are derived in continuous wave condition. Simulation results show the validity of the proposed algorithm.
