Abstract

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.
