Abstract EN
Based on the orthogonal frequency division multiplexing (OFDM) technique, an intelligent waveform is designed, which is suitable for simultaneously performing data transmission and radar sensing.
In view of the inherent high peak-to-mean envelope power ratio (PMERP) and poor peak-to-side-lobe ratio (PSLR) problems in the OFDM based radar and communication (RadCom) waveform design, we propose two technologies to deal with that.
To be specific, we adopt Gray code technology to reduce the PMERP and simultaneously choose an optimal cyclic sequence to improve the PSLR of RadCom waveform.
In our method, the optimal cyclic sequence is dynamically generated to continuously provide the best waveform according to the change of communication data.
In addition, to meet the requirements of different radar detection tasks, two simple methods are utilized to adjust the bandwidth of RadCom waveform.
To verify the advantages of the designed waveform, we conduct several simulation experiments to compare with some existing RadCom waveforms.
The results show that our designed RadCom waveform can simultaneously achieve lower PMERP and higher PSLR.
In addition, our designed RadCom waveform has a thumbtack type fuzzy function and shows the good ability to do multitarget detection.
