An interesting method for transmitting and receiving electromagnetic pulses of small time duration over a limited distance is the use of the transient response function of a wide band antenna system. Tests were conducted with one type of wide band antenna: the discone antenna. Although the method is very inefficient compared with the conventional modulated carrier wave transmission system, there does exist the possibility of measuring the time between several pulses to a high precision. Impulses of 10/sup 7/ watts peak power applied to a 2.75 meter discone anterna radiated 10/sup 6/ watt transient pulses of the order of 5 x 10/sup -6/ sec long, which were received over local areas and over 23 kilometers of sea water. A directional receiver employing separated discone antennas whose signals were mixed in a simple coincidence system is also discussed. (auth)
