Radar theory and industry convention is to match receiver bandwidth to transmitter pulse this is the maximum resolution set by the basic physics of radar other practical factors may reduce the actual resolution radar performance radar. Sonar and radar waves follow a completely different concept, but they are used for the same purpose: to detect objects through a reflection of waves.
