| ABSTRACT:
A random impulse system relates to radio detection systems and more
particularly to the generation of pulses for modulating, calibrating, and
other purposes. It is an object of the invention to provide a method and
means to generate a series of pulses of random occurrence which when used
for modulation of a carrier for transmission purposes, greatly minimizes
the possibility of enemy jamming thereof. Additionally, to provide for
the generation of a first series of pulses having very small displacement
between successive pulses and using the series of pulses to determine the
occurrence of a second series of pulses in which displacements between
successive pulses thereof are equal to random multiples of the displacement
of the first series. Additionally, to provide for a radio detection system
a first series of pulses of constant displacement suitable for calibration
of an oscillograph of the system and to provide a second series of random
pulses in coincidence with certain of the pulses of the first series and
wherein the second series of pulses may be used for modulation of a carrier
for transmission of impulses. |
