Abstract

A novel method to estimate the object velocity for random stepped frequency radar by the waveform design is proposed. The method utilises a so-called ‘complementary random code’ to modulate the transmitted waveform. Theoretical analyses show that the proposed method achieves a high precision in velocity estimation, which could meet the requirements of motion compensation. Moreover, its computational complexity can be significantly reduced, compared with the classical estimation methods. Finally, the simulations validate the effectiveness of the present method.
