According to the inherent deficiency of traditional beamformer on anti-noise and lateral resolution, this paper proposes a method based on the combination of Chirp-coded and adaptive dual focusing beamformer (CARDFB). Firstly, Chirp-coded technology is introduced to improve the transmitting average power, and then the dual focusing beamformer and adaptive beamformer are combined to obtain a higher quality beamforming signal. Finally, the signal filtered with matched filter is used for imaging. Experimental results indicate that the proposed CARDFB algorithm can achieve higher lateral resolution, better main-to-side lobe ratio and are more robust to noise compared with traditional dynamic focusing combined with adaptive focusing beamformer.
