A computationally efficient pulse compression method of Barker-coded excitation using a mismatched filter in medical ultrasound imaging
Purpose Barker-coded excitation, which is well suited for portable ultrasound imaging because it preserves frame rate and uses binary encoding, exhibits a high range sidelobe level of 1/N after pulse compression. This limitation can be mitigated by employing a mismatched filter, albeit at the cost…
