A Jamming Method for Costas Loop Carrier Synchronization Based BPSK Signals

This work is devoted to studying the jamming method of BPSK communication signal which is based on the Costas loop to achieve carrier synchronization, considering that the jamming signal will affect the carrier synchronization under certain conditions, this paper studies the jamming method from the perspective of destroying the carrier synchronization. Through theoretical analysis, the qualitative impact of jamming on the carrier synchronization loop is obtained, and then the critical jamming power of the loop lockout under different jamming signals is given by simulation. The simulation results show that: BPSK and single tone these two kinds of jamming can be used to cause the carrier synchronization loop of the receiver to lose its lock at a lower power penalty, and compared with the implementation of jamming after carrier synchronization is completed, the jamming power consumption can be greatly reduced in the process of carrier synchronization.
