Abstract: An imaging sonar using stepped-frequency linear frequency modulation (LFM) pulses can improve the range resolution. Nevertheless, the range resolution cannot be increased freely since the ping number is limited by the medium instability. Furthermore, the… read more here.

DOI: 10.1109/tcsii.2022.3142935
Abstract: A novel bandpass filter (BPF) chip using stepped-impedance stubs (SISs) embedded in coupled lines (CLs) based on the low-temperature cofired ceramic (LTCC) technology is proposed in this brief. The controllable bandwidth (BW) is mainly realized… read more here.
