Abstract
With the development of the informationization degree in weapon and equipment,
electromagnetic environment of the modern battlefield becomes more and more
complex, the spectrum resource becomes scarce. For making use of spectrum resource
effectively and guaranteeing the equipments in normal operation, we need spectrum
monitoring necessarily. The paper mainly researches the design of electromagnetic
spectrum monitoring system and the algorithm with signal processing in electromagnetic
spectrum monitoring.
The paper introduces the status quo of internal and international spectrum
management first, based on the composition of spectrum monitor device, designs the
main hardware module of the signal processor, including AD converter, signal
processing and communication control. The algorithm of signal processing in
electromagnetic spectrum monitoring is discussed emphatically, especially in signal
parameter extraction and signal demodulation, and the simulation is made in detail; On
the basis, according to the requirements of spectrum monitoring, working mode and
working flow is designed, according to the mode of frequency bands scanning, signal
analyzing and signal monitor respectively, design and implementation of software is
made in DSP.
Finally, a test of function and in
