摘要

摘要: 增加信号相参积累时间能够提高弱目标检测能力。双基地雷达长时间相参积累的关键是解决非线性相位回波的目标运动补偿问题。在波束影响可忽略的情况下，该文提出了双基地雷达距离-速度域Radon-Fourier变换（RFT）处理方法。该方法通过频域联合搜索双基地距离和速度参数空间，完成距离走动校正与脉冲积累。理论分析和仿真实验证明了其有效性。

Abstract: Increasing the coherent integration time of the signal can improve the detection of weak targets. The key to the long-time coherent integration for bistatic radar is to solve the target motion compensation from echoes with nonlinear phases. Neglecting the effect of the crossing beam, the compensation of the Radon-Fourier Transform (RFT) was studied in the range and velocity fields. In addition, the method can be operated in the frequency domain. The range walk correction and pulse accumulation were completed by jointly searching along the bistatic range and velocity parameter space. The proposed method was verified by theoretical analysis and simulations.
