SIMULATION SIGNAL GENERATING SYSTEM FOR LOCALIZATION OF JAMMER

摘要

PURPOSE: A simulated signal generating system for disturbance signal generation source position tracking is provided to perform a simulated experiment for tracking the position of a disturbance signal generation source in an environment close to the real situation. CONSTITUTION: A simulated signal generating system for disturbance signal generation is as follows. Disturbance signal simulator controller(10) generates the positional information of a satellite navigation receiver(2) and the positional information of the disturbance signal generation source in real-time. Satellite navigation signal simulator(1) inputs the positional information of the satellite navigation receiver generated from a disturbance signal simulator controller(10), and generates the satellite navigation signal depending on the positional information of the satellite navigation receiver. A disturbance signal generation controller(20) calculates the frequency change, the attenuation ratio and the phase delay respectively using the positional information of the satellite navigation receiver generated from the satellite navigation disturbance signal simulator controller and disturbance signal generating source. A signal generator(30) generates the disturbing signal using the frequency change, the attenuation ratio and the phase delay calculated from the disturbing signal generation controller. A signal coupler(40) generates the satellite navigation signal including the disturbance signal by coupling the satellite navigation signal transmitted from the satellite navigation signal simulator and the disturbance signal transmitted from the signal generator. Satellite navigation signal receives the satellite navigation signal including the disturbance signal generated from the signal coupler.
