<p>This disclosure is concerned with radio-frequency pulse generation, as for Loran type navigation transmissions and the like, wherein the transmitted pulse is generated by causing a pair of opposite poled half-cycle pulse generators to impulse-excite a tuned coupling network and antenna (or other load), the transfer function characteristics of which are adjusted to yield the desired pulse shape, with the complete cycle resulting from the pair of pulse generator half-cycles controlling, for example, the first two half cycles of the leading edge of the antenna pulse current, and the network and antenna characteristics controlling the remaining half cycles.</p> |
