摘要：
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.
