摘要

摘要: 传统OFDM雷达通常不考虑传递通信信息，该文设计出一种新的基于OFDM的雷达发射方式以实现雷达和通信的一体化，并提出一种基于通信信息补偿的目标距离速度联合高分辨估计方法。所设计的雷达发射方式，采用脉冲发射，每个脉冲由多个OFDM符号构成，在脉冲内实现通信功能；在雷达相干处理时间内，对回波进行通信信息补偿和解相干处理后，采用子空间投影方法实现对目标距离和速度的联合超分辨估计。理论分析和仿真实验表明，所提方法能够在保证通信功能的条件下，可有效实现雷达目标距离和速度的联合超分辨估计。

Abstract: The traditional OFDM radar is usually without regard to transmit communication information. A new radar transmitting pattern based on OFDM is designed to realize the integration of radar and communication. And a new method based on compensated communication information is proposed to achieve joint high-resolution estimation of targets ranges and velocities. In the designed radar transmitting pattern, the radar transmits pulse consisting of multi-OFDM symbols and the communication function is realized within the pulse. During coherent processing interval, the subspace projection method is used to obtain the joint super-resolution estimation of ranges and velocities of targets after the echo data is compensated using communication information and induced non-coherent. Theoretical analysis and simulation results show that the proposed method can obtain the joint super-resolution estimation of targets distances and velocities under the condition of guaranteeing the communication function.
