采用FRFT-OFDM的雷达通信功能共享方法
Integration of the radar and communication method with FRFT-OFDM signals
摘要
Abstract
A transmitted pattern based on pulsed fractional Fourier transform OFDM is designed to realize the integration of radar and communication.In this designed pattern,radar transmits the FRFT-OFDM pulse,and the communication function is realized within the pulse.Multiple scatter radar signal processing based on maximum likelihood is proposed.The received signal can be written as the convolution of the transmitted sequence and the weighted RCS coefficient after sampling the received signal with a certain delay,then the maximum likelihood method is applied to get the range reconstruction.Finally,FFT is applied along the pulses within a coherent processing interval.Theoretical analysis and simulation results indicate that the proposed method can improve bit error rate performance and obtain multiple scatter range reconstruction and velocities estimation.关键词
