An Automatic Control Algorithm for Sampling and Timing of Civil Radar Signal Based on DSP

Aiming at the problem of fixed period sampling control of radar signal and event triggered variable period sampling control, there are few research results at present, so a DSP based automatic control algorithm for civil radar signal sampling timing is designed. Using orthogonal intermittent sampling to implement sampling modulation on radar signals, combined with improved UNet3+network and sequence data recognition method, the modulation signal recognition is completed. Based on the recognition results, a DSP processor is designed with TTA technology as the core, integrating phase-locked loop synchronization and timing sampling technology to achieve automatic control of the signal synchronization sampling process. The test results show that the time control error of the algorithm is low, the control performance is good, and the control stability is higher than 95%. With the extension of the sampling period, the control stability does not show a downward trend.
