Abstract:

In terms of the problem that the global navigation satellite system (GNSS) receiver is vulnerable to high-power microwave (HPM) weapons, this paper analyzes the attack range and effect of different missiles' detonation with HPM bombs as the object. The author establishes a GNSS receiver irradiation model in CST-MWS, designs the circularly polarized patch antenna as the receiving carrier, and simulates the radiation field effect after the detonation of HPM bomb with the plane wave modulated by single-pulse sinusoidal signals. Based on the coupling of electromagnetic energy front door, a field-channel joint simulation method is proposed, introducing the antenna port induced voltage into the PIN diode limiter built in ADS software, which fully simulates the coupling process of the HPM from electromagnetic field to circuit. The simulation results contribute to the damage evaluation curve of the sensitive device with the peak power of the microwave source as the variable, which shows that the low noise amplifier in the radio frequency front-end circuit of the GNSS receiver is the main attack object of the HPM weapon. Take the low noise of ERA-2+ type as an example, a microwave source with a peak pulse power of 27-310 kV can cause its transistor to burn out. Meanwhile, HPM can easily trigger a spike leak in the limiter in a certain power range, and the damage caused by the spike leakage on the circuit is worthy of attention. The conclusions of the simulation can provide the basis and technical indicators for the next design of targeted electromagnetic protection for satellite navigation receivers.

Key words: high-power microwave (HPM), global navigation satellite system (GNSS) receiver, front door coupling, co-simulation, PIN diode, spike leakage
