WIDEBAND SONAR WITH PULSE COMPRESSION

摘要

A sonar transmitter includes digital logic that controls switches coupled to a primary coil of a transformer. The switches are driven to produce at least one voltage pulse across a secondary coil for the transformer to produce a series of voltage pulses approximating the desired signal. The transformer may comprise: a secondary coil having a plurality of windings arranged into a first section, a middle section, and a final section; and a primary coil winding wound only with the secondary coil windings forming the middle section.
