Integrated Radar and Communication Based on Chirp

Radar and communication integrated on the electronic war platform is an effective method to reduce the volume and electromagnetic interference.With the rise of share-aperture concepts and software-defined radio techniques,the technology of integrating communication functions with radar systems has received considerable attention in recent years.Following the principle of signal sharing,the system of integrated radar and communication is presented based on LFM signal,and the method adopts Chirp signal under same frequency modulation rate and different initial frequency.Under the premise of not affecting the radar performance,the system can transmit binary information excellently.The design of special signal make the communication signal ensconce in the radar signal.The method enhances the anti-jamming capability of the system and the low-intercept probability of signal.Finally,the resolution ability of initial frequency and the capability of demodulation of the integrated system are analyzed.The simulation result shows that the proposed integrated system has lower SER and higher robustness.
