Based on the quadratic frequency modulated (FM) signal of a maneuvering target, a novel long-time coherent integration method, i.e., Radon-fractional ambiguity function (RFRAF), is proposed to compensate the range and Doppler migrations simultaneously. By the long-time instantaneous autocorrelation function and rotating the time-frequency plane, the observation values of a maneuvering target can be well matched and accumulated as a peak in the RFRAF domain. Results of experiments with simulated and real data prove its effectiveness.
