Abstract :
Linear frequency modulated (LFM) signal is widely used in radar duo to its good characteristic. Aimed at transmitted waveform design of SAR system, a scheme of the wide-band LFM signal based on DDS technique is presented in this paper. Some factors affecting its compressed performance are also discussed. Finally, experiments results show that the proposed scheme is available.
