Radar signal sorting based on TOA key matching and square sine wave interpolation

Pulse repetition interval (PRI) is an important parameter to realize the de-interlacing of radar signals. With the increasing complexity of radar modulation methods and the increasing density of radar signal environment, the existing PRI sorting algorithm can no longer effectively realize radar signal sorting. For this reason, a comprehensive sorting algorithm based on time of arrival (TOA) midpoint matching and square sine wave interpolation is proposed. This method uses TOA midpoint matching to propose PRI periodic modulated radar signals, and uses square sine wave interpolation to sort PRI non-periodic modulated signals. The implementation results show that the integrated method can adapt to the complex signal environment and can effectively suppress the pulse loss.
