The invention belongs to the technical field of Loran C, and particularly relates to a Loran C
signal generator, which comprises a
central processing unit, wherein the
central processing unit is connected with a Loran C
timer, a
pulse control module, a Loran C generation module, a data coding modulation module and a
noise generation module, wherein the Loran C
timer receives a 10 MHz
frequency standard signal and a 1 PPS
signal of a
rubidium clock, the Loran C
timer generates a basic timing signal of the Loran C
signal generator and realizes a modulation
control function, and the
pulse control module is mainly used for determining a
phase code of a Loran C signal and controlling an Eurofix modulation quantity. The Loran C
signal generator has the Loran C signal transmission capability for generating
random noise interference, can precisely control the intensity and
noise of the transmitted signal, and provides a simulated
excitation signal for the development and debugging of a Loran C
receiver.
