Research on anti-jamming technology of pseudo-code phase modulation fuse pulse based on CPOKF

At present, it is critical to protect radar and communication systems from interference. As technology continues to advance, ensuring the stability and security of these systems is becoming more and more important to maintain normal operation and communication quality. In this paper, an anti-jamming technique based on cyclic prediction optimal Kalman filter (CPOKF) based on pseudo-code phase modulation fuse pulse is introduced. In order to improve the anti-jamming ability of the pseudo-random code pulse Doppler fuse, on the basis of the analysis of its working and anti-jamming principle, the Kalman filter parameters were optimized by using the Crested Porcupine Optimizer (CPO), and a CPOKF algorithm was proposed to simulate the pseudo-code pulsed Doppler signal under active suppression interference. The results show that the anti-interference performance index of the filtered signal of the proposed algorithm is better than that of the fixed-parameter Kalman filter signal, and the anti-interference performance is better.
