Research on fast acquisition and tracking algorithm of high dynamic weak spread spectrum signal

Phase Modulation-Fast Fourier (PM-FF) is an innovative approach. It combines the Phase Modulation Function (PMF) and the Fast Fourier Transform (FFT) to study the fast acquisition and tracking algorithm of high dynamic weak spread spectrum signals. PM-FF uses PMF to modulate signals and FFT to analyze spectrum, so as to detect and track high dynamic weak spread spectrum signals effectively. This method can not only improve the speed and accuracy of signal acquisition, but also enhance the ability to detect weak signals, especially in complex electromagnetic environments. Finally, the experimental results show that PM-FF not only significantly improves the average acquisition time, tracking accuracy, anti-interference ability and real-time performance of the model in complex environments, but also proves the reliability and feasibility of the model in high dynamic weak spread spectrum signals.
