摘要

随机频率和脉冲重复间隔敏捷(RFP A)雷达具有优异的电子对抗性能。然而，由于载波频率和脉冲重复间隔同时具有灵敏性，RFPA雷达回波的相位不再是连续的，相位的随机性大大增加了相干处理的难度。针对上述问题，本文提出了一种rfpa -氡-傅立叶变换(RFPA-RFT)方法，该方法可以联合搜索目标轨迹的距离和速度，并对敏捷载波频率和PRI引起的随机相位项进行补偿，理论分析和仿真结果验证了RFPA-RFT方法的有效性。

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.
