Abstract
A pulse compression technique using inverse filtering in frequency domain to reduce range sidelobes is proposed. When frequency-dependent attenuation is taken into account, the achievable range sidelobes associated with conventional time-domain depth-independent pulse compression methods are usually unacceptable. In contrast, as long as the truncated echoes present at the beginning of received data can be removed, the range sidelobes for the proposed method can still be controlled to a lower level by increasing the data recording time. Both simulations and experiments are performed to demonstrate the efficacy of the method and suggest that chirp excitation fits it well.
