A Novel Coherent Integration Method for Random Frequency and PRI Agile Radar
The random frequency and pulse repetition interval agile (RFP A) radar has been known to have excellent electronic counter-countermeasures performance. However, the phase of RFPA radar echoes is no longer continuous due to the simultaneous agility of carrier frequency and pulse repetition interval, and the randomness of phase greatly increases the difficulty of coherent processing. To address the above issues, an RFPA-radon-fourier transform (RFPA-RFT) method is proposed in this paper that could jointly search the range and velocity of the target trajectory, and compensate for the random phase terms caused by the agile carrier frequency and PRI. Both theoretical analysis and simulation results have validated the effectiveness of the RFPA-RFT method.
