Bistatic sonar or multistatic sonar system can collect more scattering information of targets than a monostatic sonar system. In this paper. sparse learning via iterative minimization method (SLIM) is introduced to distinguish wave components for time-domain (TD) back-propagation (BP) inverse scattering imaging improvement. Unlike the prevailing high central frequency (>100 kHz) an... https://www.kingarte.com/product-category/accessories-drain-parts/
