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.

主权项

1. A wideband sonar transmitter, comprising:
a power supply; a pair of switches; and a wideband transformer having a secondary coil for driving a transducer and a primary coil having a center tap driven by the power supply, wherein a first end of the primary coil couples to ground through a first one of the switches, and a second end of the primary coil couples to ground through a second one of the switches.
